Okay I have a 91 S13 hatch. It has a dual cam with almost 140K on it, completely stock except for intake and cat delete.. I think I'm having some sort of fuel issue, but I could be wrong.

There has been a few times when I start the car it would idle for a second or two then shut off. When I try to start it back up, it takes about 2 minutes of cranking then it will finally start. Once it starts I have to rev it a few times or it will stall out again.. after that it will idle fine.

Also, if I put the pedal to the floor in 1st and 2nd gear it feels hesitant until about 5500rpms, then it pulls like it should. I can't really tell if it does it in any other gears. It probably does but I just can't feel it.

I've replaced the spark plugs, plug wires, distributor cap and rotor. Nothing changed.

I'm thinking it is the fuel pump but I want to confirm that before I buy a new one.

Any help is appreciated. Thanks in advance,
Chase

the only way your going to find that out is if you put a fuel pressure test on it. try to duplicate the problem and see where your fuel is at. could be anything from a bad maf add or subtracting fuel, injectors staying open and flooding the motor, etc. look up stock fuel pressure, and check the entire fuel system.

as long as the fuel pressure is above 35 and lower than 50 your good..

How much should it change when I rev the engine?

it really doesnt change on my gauge but if i pinch the return line it will spike to almost 100psi
