lost power to the fuel pump

I had a problem with an aftermarket alarm on my 94Z, so the car has set dormant for 5 months. I finally pulled the alarm out, and the car would turn over, but not start. I noticed that I didnt hear the Fuel Pump kick in, did some checking and the fuel pump isnt getting power. Any suggestions? Can someone describe in detail the path i need to check for power to the fuel pump? P.S. The alarm company told me that the alarm (starter disable) would have had nothing to do with fuel pump power supply. and I checked all fuses.

Is it possible that when you did all the wiring under the dash you broke/disconnected/altered the fuel pump relay? It's located behind the driver's side kick panel. If the relay is faulty, your fuel pump will not turn on.

Talking easier install

ok my fuel pump just went out on me so what everyone told me to do is to take the rearend out and everthing to get to it, but it's alot easier to open the hatch and in the dead center of the metal behind your back seat, just lift up the padding and cut it out to get to the fuel pump. You will need a picture of it to get the precise cuts!!!
