Talk about frustrating!! We just did an engine swap in my '02 SS. Before the swap the car would run just fine (as long as you didn't notice the sound of the #7 rod slapping around in the block!). Now, when I try to start it, the fuel pump won't turn on. I bought the car with several upgrades already installed. One of which, I think, in an aftermarket fuel pump. Like I said, before the swap, the motor would start just fine and it had good fuel pressure. Now it won't turn on. Could I have a grounding problem or is there a sensor or wire I didn't hook up? Everything else seems to be working, just can't get any fuel to the engine. Thanks for any advice!!

 

Hi, See if the IGN relay is good. Swap it out with another one with the same # in the box. Think the A/C or Fan relay is the same #. Do the same with the F/P relay. Son's car has had both of them go out. Dave
