Is the car turning over? if it is check your Crank Sensor plug next to the AC compressure those are known for haven a bad connection. If that does not work check your Fuel pressure switch.

Which wires do I test going into the gas tank to see if there is power there? Im going to go to Auto Zone and buy a chiltens. When I had the tank open I could watch the pump move when the key got turned on. I can spray starting fluid and I get fire. The new pump does the same thing the old pump did. As far as the crank sensor, is it the gray plug in front of the motor, do I just unplug and plug back in? It's got a wire going into a little black thing on the front left side of the motor.
Note - the car started off and on for two days and then just completely quit (if that means anything). I just put a new pump in...same thing. I can still hear a clicking noise back there but nothing.
