Engine won't shut off

[red66toy]

Ok,
All of a sudden my engine won't turn off when I turn the key off. I take the key out and it still just keeps on running. Sometimes it will turn off just a little bit after I take the key out but most of the time it just keeps on running and I have to pull the coil wire to kill the engine. I thought that maybe it was the ignition switch going bad so I replaced it with another on I had but it still does it. Any ideas as to why the engine is still getting power after I turn off the key? Thanks dudes.

Are you talking a mojor case of run-on?

It sounds as though your alternator is managing to keep the ignition hot. Have you made any changes?

As far as wiring, I have put in a new heater recently and I had to fix the headlight wiring. I didn't mess with anyother wires while doing these things though.

Chase, START HERE! After you disconnect the coil wire and get the truck to shut off, wait a minute and try touching the wire back to the coil and see if it makes a spark. If it does, then you most likely routed a permanent hot to your coil and dont know it.

THe coil wire is black with a yellow stripe. In your other wiring projects, did you attach any wires that matched this color?

Mark, thanks. I'll check that out tomorrow. ;p

Otherwise, pull your choke to kill the engine and leave the hood down...that's what I always do

Hmm... I tried the choke thing but it didn't work. Does that mean that I have a vacuum leak? I did fix the run on problem though. Apparently it had something to do with my heater wiring job.
