Turn the key on with out turning over the motor. Do you hear the fuel pump running? Your pump might be toast.

the fuel pump should turn on for only about 1-2 seconds then turns off by itself if you only turn it on w/o turning the engine on..listen closely if you still don't hear then replace the fuel pump.

Check your fuses first. If they all check out fine, then start looking at other things..

This would be a great topic for the "Performance/Maintenance" section. I'll move it for you. You might receive more responses.

if your fuel pump isnt coming on, then a quick way to see if your pump is failing or faulty, is by jumping the FP and B+ terminal on your engines diagnostics port. You should hear the pump come on and fuel rushing in the lines if its working.

If its only working with a jumper and not working without one, then it is your Fuel Pump ECU, and I would recommend looking into bypassing the FP ECU with the 12v Fuel pump mod.
