I have recently replaced my fuel pump, fuel sending unit, fuel injectors, fuel filter and fuel pump relay. The car would run for a couple days and then the fuel pump would quit pumping. Then if you wait a few days the car will run, but now the pump will not turn on. Any advice? I'm so frustrated and confused

 

what fuel pump did you use? check fuel pressure, the cheaper ones are prone to early failure.

 

I replaced the fuel pump with an AC Delco

 

thats a good one. i would suspect and test the ignition switch. check all fuses for piece of mind, check for spark at the plugs. it is turning over right, just wont startup and run? what yr camaro?

 

I have spark, I have checked the fuses, I have checked just about everything I could think of. The fuel pump isn't kicking on. It is a 92

 

need to find out if your getting power to the pump, is there power to the relay? found this but i dont know how much truth there is to it. Check behind the battery. You will see something bolted to the fender with 2 wires coming out of it. UNCLIP that assembly and you will find the fuse.

 

I am getting power to the back of the car where the fuel sending unit plugs but nothing after I plug it up. I dunno what else to check.
