Hi guys. I'm finally getting around to restoring my 92 non turbo FWD talon, which has been garage stored for over 8 years (hence all my recent posts on the forum). Can some explain the fuel circuit to me Specifically, is the fuel pump designed to turn on and off when car is running whenever fuel supply/pressure is needed or does it run constantly? I'm asking because I may need to bypass the electrical and want to hook it up to something with voltage whenever car is turned on. Will this wear out my fuel pump with it always running?

That makes sense. Any ideas on which fuse I could tap into at the under dash fuse box that would only be live when engine is running. Would be nice to be able to listen to radio with key in ACC position with out pump running. Thanks again.

Sounds like it was bypassed already and he is trying to get it back to factory. Which one is it Ed?

Both sort of. Let me explain, The reason I have to bypass is because on the stock wiring harness to the fuel pump I am not receiving any voltage at the tank. Doesn't matter the key position. I replaced the Fuel Injection Relay but still nothing. As a test, I bypassed the hot wire to fuel pump with a new wire to connected it to something I new worked (the radio), and voila everything runs fine. I'm not sure whats going on (perhaps the wiring running through the car has been damaged?) It there anything else I should check? My work-around is to just connect the bypass wire to an appropriate landing point on the fuse box (which sounds like the MPI?) Appreciate any advice on this.

Thanks Stephen. You mention I can test for Power and ground at the rely very easily. Can you detail the procedure I would use to do this test? test points, engine/ignition condition, etc.
