Hi there , i have replaced the in tank electric fuel pump and at times it will keep running with the key off ,,also the wire harness was rewired because one was not on the shelf ,,any one gone this way before and what was the fix. Thanks guys

Probably a sticking relay. Rewired which part of the harness because what wasn't on the shelf? 07-11-2010 05:42 PM

Thanks for the reply Randy, i didnt do the work myself but the connector end on the pump was corroded and the wires were worn almost through a ways back,,Question i unplugged all the fuses and relays in the fuse box under the hood is there any other place for relays to look Thanks again

My mistake on your truck. The lift pump is controlled directly from the ECM. If everything is wired correctly, then you probably have an ECM going bad. 07-11-2010 05:47 PM

Welcome to the forum! I moved your thread over here, that way, others who may be having the same issue will be able to find the info they need on their techincal question as well, but good luck with that, Randy is definitely the man to help! :)

ECM = Electronic Control Module. Basically, your truck computer.
