To whoever may find and read this, any help is appreciated! I was driving and my car suddenly shut off. I have been having a problem with a hesitation during light throttle as well. With these two things and the fact that my fuel pump was not priming after my car died out, I figured I had a bad fuel pump and that was the cause of the problems I have been having. I replaced my fuel pump with a new one- I am having the same problem. When I turn the car on, there is no sound coming from the back of my car where the pump is. The engine is cranking the way it does if you remove the fuel pump relay- it goes and goes but does not turn over. I have changed out relays, replaced the pump, checked the fuses.- I don't know what to do next.
One other thing was the clip that connects the fuel pump unit to the chasis in the back. I looked at it when I went to unplug it and it seemed like it was melting. I crimped the wires together, the way they would be in the male and female connections- but i have still been having the same problem after doing that.
Please Help.

I would make sure you're getting power to the fuel pump. After that, I would start checking the relay base for power and also check to make sure the ECU is activating the relay.
Once you can eliminate wiring and the ECU, you're back down to the pump itself. Given the age of the age of the car, it could be a matter of rust/gunk in the tank interfering with the pump.
Also, what brand of fuel pump did you put in place of the old stock unit?

Re: fuel pump/ electrical problem (athomas08)
this happend to me also. hesitated and died.i was about to replace the pump too but i decided to check the wirings, first, particularly the MAF connector wiring.
i started the engine and wiggled the wires in the engine and yes, i was able to determine that my MAF connector was lossing contact.
i am not saying that this is the solution to your prob, but just another option to consider.
happy hunting!
