Default Re: Rattling and then my truck won't shut off

Yikes what a mess. Ok, first things first, your friend saying the trucks is "hard idling"... stop listening to him. I don't know what that is supposed to mean, but it is likely a cool sounding phrase to mean "I don't know what it is so here is this cool sounding term!".

The shaking-rattle-n-roll sounds like you have multiple spark plugs not firing at all, or multiple cylinders experiencing massive detonation. Pull all the plugs and wires and inspect their condition.

Theory #2, Something is funky with the key cylinder and its causing interupted power to the ignition and fuel pump. But this sounds too "consistently unstable" to be that. It would however explain not shutting off.

Jump start it and see what happens. The battery could be dead or something else is screwed up, like the key cylinder.

A lot of this sounds like the key cylinder being retarded but at the same time makes no sense.
