hey, there are several things that could have gone wrong with the installation of the pump... is your engine cranking at all??? After you crank it, go outside the car, and sit down by the frame... do you hear the pump? If it cranks with out starting, double check that you hooked up the pump facing the right way for flow, and also that it is hooked up right, as far as power, and ground. Let me know what you find...

yeah tha car turnes over but wont catch....i thought that when i turn the key to the on position the pump should come on....i do hear it when i turn the key off from trying to crank it but if i tap on the filter it seems like it is emptie when it should be full of fuel....it makes me think that the pump is either pumping the wrong way because i might have the positive and negative wires on the wrong leads on the pump...cant mess with it because of bad weather though

yeah, you could have the pump lines swapped, hypothetically, but I dont know how you would do that.. I think that you could have the pump turned around. When you took off the old one, did you make note of how it was in there and everything? Did you use the factory bracets to mount up the new one? B/C if it is swapped, you would be trying to suck fuel from the motor and put it in the gas tank, hence the fuel filter would seem empty like you described.
