[QUOTE="Jbsmith580, post: 439304, member: 21218"] The fuel pump isn’t pumping any fluid. Matter of fact it isn’t making any noise any more. I think it’s done for. I don’t know what resistance to look for across the pump and ground though but I saw someone say somewhere that their pump to ground read 2 ohms and is working and mine is way higher than that. I did rig a hose to the fuel line on top of the tank to an empty fuel container and jumped 12v from the battery (to be extra sure) to the pin in the relay box for the pump power, and the pump did nothing. Even after I removed it I plugged it back into the harness and set it on the concrete and turned the key to on and heard the relay click, but the pump did absolutely nothing, no noise or gurgling no high pitch squeals it’s just dead now. I’m off tomorrow and have to return it to the big rock candy mountain via UPS pickup but I’ll get up early enough to jump 12v- and 12v+ straight from the battery to further prove to myself it’s gone [/QUOTE]
