hey to all my friends from long ago, and hello to all the new guys here too, long time no post for me! hope you are all doing well.
so yesterday I went to do my monthly hibernation start up to let my 01 cobra run for 15-20 min and it was a no go. No fuel pressure, no longer hear the fuel pump when I turn the ignition on. I made sure the fuse was good, everything seems to be plugged in and the inertia switch has not been tripped.
my question is: if I were to check for voltage at the plug between the rear bumper and fuel tank, what should I be seeing for voltage and on which pin(s)?

Not acure but a temp fix. If the tank pump is not working it can sometimes be to,wear and accumulation of stuff on the pump internals. Basically the pump won't start with out assistance.
If you take a rubber malet and hit the tank and the pump starts, would have your temp,fix and have determined the pump is the problem. Replace the pump.

If this is the problem, you should be able to get through hibernation. Change pump soon.

thank you for the reply, I got a loaner FPDM from my local parts store and tried it.. no change. So I dropped the tank and swapped out the pump this morn. All set, up and running!
