I am having issues with my fuel pump install on my 96 cobra. I upgraded my fuel pump to a Walbro 255, after installation the fuel pump kicked on once I turned the key, and that was the last time it pumped. there is no fuel pressure at the rails. I have done the following....

-replaced fuel filter (installed correctly)
-checked all lines
-checked fuses
-checked fuel pump inertia switch
-replaced relay (located behind glove box)
-pulled pump, tested, and functioning properly
-checked and there is no power going to the pump

Does anyone know what the problem could be?

 

Follow your wires from the pump back to the front of the car. You may have pinched them somewhere. Check for power coming from the relay. If you have power then you know you have a bad wire going to the pump somewhere.

 

Thanks i will try that tonight.
