Question type: Maintenance & Repair
Last night after shutting truck off there was a
humming sound coming from underneath near cab
and bed. This morning truck is deader than a door
nail. Any ideas? Happened before and had it
jumped worked fine.

That's about where the fuel pump/gas tank is, along frame rail just behind cab and under bed. Could be a bad fuel pump relay causing it to run when vehicle off. Turn ignition key to run and listen for fuel pump, is it the same as your humming?

I had to have it jumped but soon as I shut off the noise continues and dead again.
