Car will drive some days then it will not start. I changed the fuel pump the same day and the car started fine for a day or so now it will not start again. I cannot hear the fuel pump come on again. What could be the problem now? Please help!

What is the sub-model? (Base, LS, LS Coupe)? And is it automatic or standard transmission?

Just wondering off hand, did you replace the fuel filter or any other components during the repair? Do you have access to a fuel pressure gauge and what was the condition of the connections on the top of the fuel tank? Was the top of the tank very dirty and connector hard to pull apart?

It is a bar model automatic transmission and no the connectors did not have sort around them or hard to pull apart. Well the gas pump seal so the pump from pumping. I also checked the relay and it seemed fine. I did not change the fuel filter though.

Base model. Did not have dirt around it. Will the gas pump seal so it from pumping. Whatever the problem is I am not getting fire to the fuel pump to even make it cut on.
What components affect that?

Assuming you have checked the fuel pump circuits with a test light, you'll have to go to the fuel pump relay next, there should be a fuse box under the hood with relays and fuses. They should be labelled.
