I have a 99 F350 4X4, I'm pretty sure it's a late 99 since the door panel build date is 4/99 and I also have an AIH.
So it rained last night, not hard, but a steady light rain. I had the block heater plugged in all night, temperature was around the 40`s, turned it on this morning and it started like a champ, everything sounded good. Drove around town for maybe 10 minutes, got to where I was going and turned the key to the off position and the engine keeps running. Radio turns off and so does A/C but dash lights stay on and engine keeps idling. It sounds really good, no clanking or clicking or rattling or anything, it purrs like kitty but just won't shut off. I turn turning their key back to the on positing then back to the off position, I try jiggling it and everything but the engine stays on.
I got it to turn off by pulling fuse 24 which is labeled PCM Power. (I have a 2000 owners manual even though my truck is a 99, I'm assuming their the same.) After the engine dies my dash gauges continue to receive power as well as the lights such as the abs, seatbelt and a couple other lights all within the dash.
So to me it sounds like my ignition cylinder is bad or going out at least, I bought the truck used and I have 2 keys, one for the doors and one for the ignition so I think it's already been replaced once.
So I'm just wondering if it is the ignition cylinder or if y'all have other ideas on what it might be? And if anyone else has had this problem? Also is pulling the relay the best way to turn the truck off or will that mess something up?
And I tried turning the truck back on and it starts great, but I have to pull the fuse to get it to turn off again.
Thanks for any and all help.
