quick help. truck wont shut off, ***update***

[gonger]

1989 suburban, trucks sitting in driveway runnning as I type, I shut off ignitition and it keeps running, Is there a relays switch anywhere, when I turn key off, all accessories/ac do turn off, making me think theres a relay?

thanks in advance for any tips.

update....
well I was able to track it down from smell last night, not sure, but from looking in chilton book, its called "hot fuel module" it looks like a small circuit board . I can remove the small module and the truck starts/stops like normal, but I think if the truck sat for a while it wouldnt have the fuel presure to start. Now my only worry is that theres a short somewhere elese that cause this to fail?

So I did some searching, and find little info on hot fuel module, maybe its not needed? is it a emmisions thing? cant find replacment.

I'm not much help On the fuelie trucks never had to work on them it may be your column is it a tilt ??? sometimes if the column is real loose and sloppy it makes it to where the switch doesn't get it's full range of motion

the igniton switch is located on the top of steering column near the floor with a rod that runs up to the tumbler sometimes the switch can go bad or the rod could bindup/break/come loose

I'll second the iggy switch. 20 minute job to replace...

Our 88XJ used a GM column and I replaced the iggy switch in that about 6 times before getting rid of it.

That kind of thing has usually been a result of a bad ignition switch for me (on several make and models of vehicles).
