Car shuts off when under half a tank of gas
We tried cleaning the fuel tank but nothing happened

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

This sounds like a fuel pump or a fuel filter issue. You can try taking both out, see if they're clogged. Good luck!

[unreal spindle]

Can affirm with LayZey i would check your fuel pump or fuel filter. Easy way to check which one it is is to bang on the gas tank with a dead blow hammer while you try to start the car

If it starts, its probably a fuel pump issue, if not, look at the filter

[sharp tiger]

Some cars have split tanks with 2 gauges to measure how much fuel is in the tank, if one of them is stuck at the top, the car shows half a tank of fuel left while actually being empty

I’d try to fill it up to the max, try seeing if the amount that you can put in is actually only half a tank or more

[slate swan]

@sharp tiger @unreal spindle @green thicket I have replaced both the fuel pump and filters

It’s my grandfathers car and I’m down for a short time so trying to figure this out before I go. Will take the car and fill it up, it’s at a half tank right now so if I fill it it should go to 30 liters

I wonder if its a pressure issue?

[narrow iris]

It could be. Amongst what others Ahmad stated

This gen of Honda does use a fuel filter, that can be found in the engine bay by the fire wall.

[slate swan]

Yeah but we have replaced it

[narrow iris]

Ahhh ok

[slate swan]

This car has been trouble trouble

[narrow iris]

Which is odd because this is a great gen of accord.

You have a fuel pressure regulator for this car too. It is attached to the fuel line in the engine bay. However if this was bad, I would assume it would cause issues at any fuel level in the tank

I’m leaning towards fuel pump. Being the issue

Fuel pump for this car is cheap. Assuming this is the 4 cylinder, here you can find the parts

We replaced the fuel pump

I just filled it up and the gauge is correct. Gas stopped at 7 galls which is half a tank

[narrow iris]

I would put a pressure gauge on the fuel line coming into the fuel rail..

[slate swan]

Once we get to below half a tank?

We also live in another country in Central America so it’s not easy to get parts

[narrow iris]

I would do an array of measurements

[sharp tiger]

Have you drained the tank?

This might sound stupid but fuel is lighter than water.. maybe water ended up in the tank somehow

[slate swan]

How do I do that. and how long does it take

[sharp tiger]

easiest way would be to stick a hose into the tank attached to a pump probably

[slate swan]

He claims they took the fuel tank out so there can’t be any water in there

[slate swan]

Oh hey you are on this thread

[slate swan]

This is where we were about two years ago

[narrow iris]

So just to reiterate it starts fine and runs fine when it’s over half a tank of fuel?

[gray coyote]

Tank could be pulling massive vacuum under half

[steady junco]

This does not sound like a very healthy engine

Can you disable the fuel pump and crank it

I just want to hear it cranking without trying to fire

You could also unplug the injectors

[slate swan]

Yes

[slate swan]

That’s how it was two years ago. Starts up fine with over half a tank
