I bought a 1993 240sx and my problem is that the engine keeps flooding with fuel I’m getting compression I’m getting spark when I crank the engine it keeps trying to start but won’t turn over and the injectors don’t leak you can’t just hear the gas filling up the cylinders

Okay at least you got it in the right section... so I will bite.

Check your injector o-rings.

They are a common point of failure causing excess fuel to seep into the cylinder and flood it w fuel. Cheap and easy to replace, if you haven't done so already :2c:

We do have a small question thread for this very reason...

So what your sayn to be clear is, the engine turns over, your getting spark and fuel, but way too much gas is entering the cylinder?

remove the fuel rail from the intake manifold, while leaving the fuel lines attached.

Cycle the key to the "on" position, but do not crank the engine.

Inspect the fuel rail for leakage.






Also, are you running an aftermarket FPR?

So when I try to crank the car basically it makes this pumping noise and the rpm gauge starts to flicker like it’s trying to start but won’t

Oh god......

You have spark at the plugs?

Do you have fuel pressure?

Are your injectors firing?


Lets keep this simple

Stuck fuel injector. It must be replace. Take your fuel rail out but not the injector and turn ignition on. There should be no fuel spraying and no leak on any fuel unjector.
