[QUOTE="mach1matt, post: 15812747, member: 182277"] Good evening everyone. I’m having a strange issue with my 91 efi 5.0/AOD swapped notch. The fuel pump will run continuously when I turn the engine off, regardless of key position. It doesn’t always do it, just most of the time. If I unhook the battery for 5 or so minutes and hook it back up it will turn off. Sometimes when I shut the door or open it the pump will shut off or turn on. I tried investigating this problem before and noticed the relay under the drivers seat was missing and just had a plastic cap on the plug. The pump will prime though when the key is turned on. I have no clue what year the donor car was that all the parts came out of. I am absolutely baffled on what could be causing this issue. Wiring is not my strong suit, so any help or guidance would be greatly appreciated. Thanks in advance.
