Fuel Pump Keeps running
Got an issue here that I haven't had any luck in finding a solution for... YES, I've tried the searches on several forums....
My wife has a 2001 Chevy Suburban LT, 4x2; this last Thursday night she came home, shut off the truck & upon removing the key, some thing kept whining under the truck. Once I got home, listened to the sound & laid down under the middle of the drivers side I determined it was the fuel pump.
I've read about the Oil Pressure Sensor being related to this is some capacity, but during some trouble shooting today, I don't think it is. I unplugged the Oil Pressure Sensor & the pump started running again, once the positive was reconnected at the battery.
Other Google searches have made mention of a Fuel pump flow control module, but I have yet to find any posts that talk about it causing the fuel pump to run constantly even when the keys are out of the ignition.
I really could use some assistance.
Thanks

Have you done any work recently what so ever under the hood or on the vehicle? there used to be a by-pass wire on the fuel pump for the previous body style that you could by-pass the fuse to power up the fuel pump but I don't think it was on the 2001 but it could be... the wire was bundled up near the fuse box but it would have to be intentionally connected....
