1988 Toyota AllTrac Celica needs replacement fuel system

[feral sparrow]

Good day yall, I have a car that won’t start, I believe it’s an electrical issue however idk how to go about it. The two vids linked are the most amount of progress I got with sim context as to what I’m doing in there. Some extra context is I’ve been currently taking out as much as I can from the engine bay to see what’s wrong, and most of it is wiring and electrical; cut wires, missing wires, ports that don’t connect to anything etc. right now I’m just trying to see if there’s any life and get it cranked rn. This is my first car and I love it even tho it never worked on me yet. Any ideas or advice,

[mossy acorn]

Holy-that car is in pieces mate, but i suppose it'll work well for learning

Try and focus on air, fuel, and spark to get it cranking

[feral sparrow]

I took everything out to find what’s wrong, I am focusing on those, but right now I’m focused on trying to get life, since there is no life without crank

[mossy acorn]

Define life

Have you tried jumping it?

Have you verified the state of the battery?

Have you checked the grounding points for the battery?

Just a couple things to think about

Please do keep me updated-I'm doing a similar process with my miata. It starts, but won't drive

[feral sparrow]

So in the vid where you hear the beeping is the most life I got out of this thing, the starter tried to do a thing. That’s what I mean by life.

It’s not starting

[mossy acorn]

Figured that, you're looking at electrical then

Did you try jumping it or replacing the battery/starter solenoid/starter assembly whatever the frick you call it?

[feral sparrow]

The starter is fine as I tested that outside of the car, battery is definitely a problem, and so is the wiring since the previous owner was messing with the wiring harness, there’s cut and missing wires

Me verifying the starter is alive

[mossy acorn]

The starter being fine is a good start, I'd toss it back in (if you haven't already) along with a new battery

[feral sparrow]

That’s what was in the car, when I turned the key the second time you can hear it trying to engage

It’s that clack you hear

[mossy acorn]

It probably isn't getting enough voltage or power, whatever you electricians call it lol

Jumping it with a big car like a truck or cargo van might help

Plus just going over the wiring harness

A couple people here have access to databases that have wiring diagrams for your car

Or you could go through google till you find one

Also, check your oil and coolant levels to make sure they're good before you start it up

[feral sparrow]

In the video I’m using a rv boat battery since I believe I fried the previous battery by accidentally putting the polarities on the charger. Lucky it didn’t explode. I was testing the starter alone with that jank setup you saw in the starter vid to try to get the flywheel to spin, but the battery started smoking, so that one’s done

[glacial estuary]

GG @feral sparrow, you just advanced to level 2! Chat more to level up and earn top roles!

[feral sparrow]

I’m not worried about coolant as much now (stupid ik) as I’m just trying to run the engine for a quick sec to see if it’s even worth my time trying to fix fix. Oils inaccurate tho. Out of everything, oil is perfect surprisingly

[mossy acorn]

Oil is the more important one, it'll run fine without coolant for a good while

I assume you just want to do a compression test?

[feral sparrow]

Exactly my thought process.

[mossy acorn]

Also am i tripping or is your intake just a gaping hole?

[feral sparrow]

I took out EVERYTHING I could

Gimme a sec, I’ll take a vid

[mossy acorn]

Good lord, okay

[mossy acorn]

Holy-

[mossy acorn]

My brother in christ

That is a lot of freaking parts

[feral sparrow]

This car was not working, so I took as much out to find problems

[mossy acorn]

I suppose

Normally leaving things in helps unless they're obviously broken

[feral sparrow]

I get that, however with as many cut/broken/missing hoses/wires, this was the way I thought would be best

[mossy acorn]

Get the broken crap out, yes

[feral sparrow]

No, to find the other broken shit hidden beneath

[mossy acorn]

I'd go through and make a checklist of everything you took off the car

And see if any of it is related to the car being able to crank

[feral sparrow]

I have vids of everything I took out

[mossy acorn]

And then put those parts back on

[feral sparrow]

Everything related to crank I believe I put back in to test crank

[mossy acorn]

Fair enough

I'm gonna go trawl through some 'yota forums

And see what i can find

[feral sparrow]

I have the wiring diagram book, I just left it in my uni dorm, 1200 miles away….

[feral sparrow]

Thank you

[mossy acorn]

Yup!

[mossy acorn]

I hate when that happens

Good luck man, I'll get back to you sometime soon on common things that break on these cars

[feral sparrow]

Thank you sir. Take care and good night from my side of the world

[mossy acorn]

Yessir, it's night where I'm at as well, and I've got work in the morning or I'd look tonight lol

[feral sparrow]

Yo, something I forgot to mention was my fam tried to push start the car before hand by pulling it at 30mph and dropping the clutch, but the wheels locked up every time they did, they destroyed the passenger back tire doing so

[feral sparrow]

So currently debating on wether or not my engine is currently locked

[glacial estuary]

GG @feral sparrow, you just advanced to level 3! Chat more to level up and earn top roles!

[feral sparrow]

So as of this moment I’m thinking on how to go about this, the engine is either fine, or i rebuild it or replace it

[mossy acorn]

Jesus

Sorry bro I got busy w work

Any updates?

[feral sparrow]

Nah, I’ve been away from the car due to life and family

[mossy acorn]

Ah, it happens

[feral sparrow]

Also, why do you hate Hyundai? XD

[feral sparrow]

My engine isn’t locked

[feral sparrow]

So I believe my next step is to see if I get compression. And for that I think I need to reinstall the throttle body back on to my intake manifold, and hook up a functional battery and try that

[mossy acorn]

Pretty much

Best of luck man

[mossy acorn]

They make horrible cars that i would totally buy if they were, you know, not fire hazards

[feral sparrow]

Understandable

[feral sparrow]

Ok, now I have 10 starlight days of being with this car, Les do dis.
My priorities are spark, gas, air. Right now I’m trying to see if it sparks, hopefully this new battery will get it to crank properly

[feral sparrow]

My starter is “starting”, but isn’t following through

[mossy acorn]

Damn-do you know if you have good gas in the car?

[feral sparrow]

I forgot to update, I’m now trying to see why I’m not getting spark

[feral sparrow]

So after fafoing and asking around, I think I’m not getting spark due to a fuse, worn out distributor cap and rotor, ecu isn’t sending out the spark signal or something like that

[glacial estuary]

GG @feral sparrow, you just advanced to level 4! Chat more to level up and earn top roles!

[feral sparrow]

So how would I deduce if this is a bad distributor? I’m getting a multimeter tmr to see if my ecu isn’t sending out signals. Any electrical advice would be appreciated

1988 Toyota AllTrac Celica no Spark

[mossy acorn]

Mechanical stuff is what I'm better at-I have very little electrical experience. However, I think @fair plover was an electrician at one point, and @unreal igloo is also one i think

[unreal igloo]

a timing gun works well for that

Starting with wire 1, connect to each one and see if the light lights up
if it does, there is enough to trigger it
When they fail you usually have no spark at all vs just a low current

if you take the distributer cap off, look at the contacts

are any broken or worn?

if it's an ecu problem, without bringing it in you're shit outta luck

assuming you don't have the equipment and knowhow for that

[fair plover]

On this gen Celica it won’t be your ecu sending out a signal

[feral sparrow]

Oh?

I was about to buy an ecu, but should I still get a multimeter?

[fair plover]

Your distributor is a mechanical pick up. So it rides on timing some where.

I would check your distributer entirely first before buying more parts

[feral sparrow]

Well the rotor is spinning

[fair plover]

That’s a good thing

You don’t have anything broken in the motor lol

[feral sparrow]

But should I still get the multimeter? I’m at the store rn with it in my cart. Should I still get it?

[fair plover]

A multimeter is a great tool to have

[fair plover]

Yeah the rotor is moving. So when it’s all together you get no spark at all?

Have you placed a cable to ground?

[fair plover]

Spark plug cable to ground*

[feral sparrow]

No, but would that just mean to put an electrode into the spark socket and bring it to exposed metal on the car?

Could I do it with the ignition coil plug?

[fair plover]

You definitely can

Just keep in mind it may bite you so I would hold it to the block with a good pair of pliers while someone cranks the car lol

Also, I see that green wire all frayed going into the ignition coil block

Looks suspect for sure

[feral sparrow]

That green wire feeds into the signal of my starter

[undone gate]

i wanna see this celica run

[fair plover]

Find anything OP?

[feral sparrow]

As of rn im learning on how to use the multimeter

[feral sparrow]

Also here’s something I think the previous owners were trying to do something with the starter

http://www.st162.net/index.php?threads/starter-relay-mod-for-dummies.7760/

[glacial estuary]

GG @feral sparrow, you just advanced to level 5! Chat more to level up and earn top roles!

[feral sparrow]

As the first car I bought, I also want to see this car run

[undone gate]

broken wires, shorts, grounds or a defective stop switch

[feral sparrow]

Probably all of the above

Also when cranking no fuel pressure. I put the bottle to catch any that flowed out, but nothing

[feral sparrow]

My fuel pump only works the opposite way

[feral sparrow]

Meaning when I hooked it up to a battery it wouldn’t pump in the right direction, only the opposite direction

[fair plover]

It’s a DC motor so your changing direction of current when you have it hooked up that way

But it sounds like something is connected wrong lol

[feral sparrow]

It went both ways, but the only direction that was actually showing life was it going the opposite direction, I think

[fair plover]

So maybe your fuel lines are backwards

Or switched somewhere

[feral sparrow]

Got spark through the ignition coil

[feral sparrow]

Could my ignition coil be weak or something?

I believe all I need to fix now is fuel

[feral sparrow]

Welp

[undone gate]

😭

[feral sparrow]

So I followed the form at replied message and it’s not doing the thing, maybe the signal wire still isn’t putting out enough power

[feral sparrow]

GOT IT

Nvm

[fair plover]

You got it. That’s the starter relay for the starter motor. Be careful actuating it with your screwdriver. That is high current.

But it seems your relay is not getting the 12v signal to excite the coil.

[feral sparrow]

Ya I’m aware and don’t wanna touch it, I was a bit careless rewatching, but any ideas on how to supply 12v to the relay?

I’m still a noob at electrical, I wanna get better

[fair plover]

For testing?

Or where it comes from originally

[fair plover]

And don’t sweat it, you’re doing great just do things safe lol.

[feral sparrow]

To start the car when I turn the ignition, maybe from it’s original stand point, or some other source

[fair plover]

The 12volt signal probably comes from your ignition.

https://a.co/d/gBPcoz9

I’d recommend you getting this, these Haynes Manuals always have electrical schematics that you can most definitely use to trace your issues

[feral sparrow]

My friend has this

[feral sparrow]

But this manual is specifically not for the alltrac, I have an alltrac.

https://www.alltrac.net/index.php?threads/engine-no-crank-no-start-possible-code-12.50866/

Found a mod to the relay mod

[fair plover]

So you’re telling me the electrical is that much different from the standard Celica when compared to the All Trac?

I’m sure you have the 3SGTE but how it starts I’m sure is the same.

In regards to the 3SGE

[feral sparrow]

It should be the same

I’ll see

[fair plover]

If you need help with electrical schematic analysis let me know,

[feral sparrow]

I just need help with symbols n shit, but it’s raining and can’t do shit

[feral sparrow]

1988 Toyota AllTrac Celica dorsnt pump fuel

[feral sparrow]

Ordered the new fuel pump

[glacial estuary]

GG @feral sparrow, you just advanced to level 6! Chat more to level up and earn top roles!

[feral sparrow]

Stupid idea, could I just get a cable from my battery, hook it up mechanically to my ignition in a way where it brings a terminal to a contact then bounces back with the ignition spring?

[feral sparrow]

1988 Toyota AllTrac Celica doesn’t pump fuel

Fixed a typo

[fair plover]

Your ignition switch controls a relay for a reason. It’s so that all that current doesn’t go through your ignition switch, rather it goes through the relay instead.

[feral sparrow]

Not electrically, just using the physical turning of the key to turn a lever to bridge the circuit.

[fair plover]

I guess you could

[feral sparrow]

But what would be my options to send a 12v signal to my starter rn? Skechy ignition lever, redo the whole ignition circuit, or something.

Wait, question

Maybe my ground wasn’t ground enough

[fair plover]

It would be fine since all grounds eventually connect some where.

A good ground is an unpainted surface

[feral sparrow]

I thought that the bolt to the body was good, guess not

[feral sparrow]

Don’t worry, the vice grips are holding rubber

That was the problem, my ground wasn’t ground enough

[fair plover]

Cool

[feral sparrow]

Now I just need to fix fuel, figure out where a bunch of these cables connectors went, fix these missing and/or broken tubes and hoses

[feral sparrow]

I’m going to be away from this car for several months now as I’m going outta state for the time being and will return. If need to be deleted please let me know

[feral sparrow]

Re, only commenting so it’s still in my list on the side, disregard

[feral sparrow]

1988 Toyota AllTrac Celica is put on hold till i return home

1988 Toyota AllTrac Celica needs replacement fuel system

[feral sparrow]

IVE RETURNED and have looked at the car a lil bit more, the fuel tank is covered in rust in the inside and has some weird rubbery substance with the rust. My uncle was saying that the rubber could be solidified gasoline and it apparently likes to creep. Can’t find a gas tank for this car and I might be looking for more performance like solutions. Any ideas?

[feral sparrow]

Here you can see how coated the tank is

[fair plover]

If you can’t find a tank, which I’m sure has proved to be difficult, I would use a fuel cell

Maybe relocate it to the trunk. Usually that’s a performance car option but if you can’t find a tank, it is an option.

How much gas is in the tank? Can you restore the tank?

[fair plover]

Nvm I just watched the video, that is pretty bad lol

[feral sparrow]

I have a friend who told me to just fill it with vinegar and shake it, but I cleaned iron with vinegar before for rust and it made it vulnerable to rerust immediately

[fair plover]

I would trash it. I don’t think the effort is worth it

[feral sparrow]

Ok, so is a fuel cell one of those boxy racing fuel tanks?

[fair plover]

You got it

I mean, if you can find a tank, I would put a factory tank in but if not a fuel cell.

When it comes to my Datsun, that is my plan, pulling the original tank and installing a fuel cell

[feral sparrow]

There’s no finding this tank, ppl have been having this issue since 05. It’s either restore the tank or Jerry rig one

[fair plover]

Ahh ok

[fair plover]

[feral sparrow]

Unfortunately. Look up Toyota st165 gas tank. You won’t find it. I was only able to find a forum post saying how different the gas tanks are within the 2 models of this car
