When you hook the pressure test guage to shrader valve on fuel rail what it reads is what the pressure is from pump, around 60 p.s.i. all you need to do is hook up the guage and turn on key, you do not have to turn engine over, and if pump is good it will shoot up to 58 or 60 right now.

the fuel pressure if leaking could cause this the regulator is located under the intake plenum but you should smell gas .if you dont then most likely the pump is bad ,the pump will come on for 2 seconds when the key is on then go off it will not stay on with just the key on only when you crank it will it .so have your fuel pressure checked with a gauge.

This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

Try replacing oil pressure switch. Your oil pressure switch controls fuel pump. (safety issue) in case of roll over or accident so fuel pump doesn't run while engine stalled or of.

Fuel injected or carb? Make sure fuel line itself is clear. Some pumps are designed to self regulate (carb systems) some continually pump and a psi regulator sends back the excess fuel back to the tank (fuel inj systems) If the line is obstructed then pump can't deliver fuel fulltime.

If you think pump is not on consistent, try running a dedicated wire through a switch directly to the pump. If it works then you are looking for an electrical fault going to pump. Good luck.

I have a 93 altima that will crank but will not start...about a couple months ago i went to my work and shut off my car. it was running fine when i shut it off.. when i came back out and started my car...


this year model is notorious for fuel related probs...check the remainder of the fuel system, injectors, and the fuel pressure regulator also verify that the fuel pump is actually running and getting the correct amount of power to the pump itself..... it may not be bad just not getting enough power
