Exclamation * Fuel Pump wiring check *

Fuel delivery issue -- No power to fuel pump.

--I checked the fuel pump wiring harness -- nothing lit up on my volt tester on any of the four (it has a four pin connection to the fuel pump hanger). I'm 99% sure that it's an electrical problem...but i didn't replace the hanger when i did the fuel pump. Never done a live wire rig to the pump to make sure though...anybody done that one??

Let me know if you've run into a wiring issue for the pump or if you know any tricks. I had to do this one time before -- turned out to be a grounded wire...not sure though -- it'll be a headache if i have to trace down the wires.

thanks ya'll
