the car has spark compression and fuel but will only run on cylinders 2 and 4 .
the spark plugs are brand new, the icm is brand new, the coils work fine as well as the injectors.
p0300 engine code thats all i could get from my scanner
honestly completely lost rn any help would be great

...
check the spark plug wires and ensure they’re connected and in decent condition
tidal island
Did

also verify the fuel injectors for the cylinders out of operation are functioning

did you inspect wiring harness and connectors related to the faulty cylinders
tidal island
i didn't see anything visually but that is a possibility
carmine gull
if it persists check the compression to ensure there arent any issues with the valves or piston rings
tidal island
Fron what i heard it just kinda happened all of the suddeb
carmine gull
and maybe even the fuel pressure
tidal island
compression is good
carmine gull
then it’s an electrical issue or component failure
if it was sudden
check wiring harness, ignition coils, or icm
distributor cap and rotor could show signs of damage as well
fuel pressure regulator could have malfunctioned
if it has an maf sensor make sure that works
and check your vacuum lines
tidal island
Icm and ignition coils are new

Still working on fuel stuff but i dont think that can cause a dead cylinder
carmine gull
