98 yukon, Key doesn't shut engine or dash off when turned to off position.

Hey Everyone! Have the famous 98 Yukon, This morning I started the engine and couldn't turn it off with the key, dash wouldn't power off either. Had to pull the ignition coil to cap! Anyone know why this may have happened? Only thing I can think of is that the battery terminal wires were removed and put back on, but that doesn't make a whole lot sense to me. Any advise is appreciated! I need to start digging into this soon.

Sounds like it's in the column at the ignition switch. Instead of playing with pulling a coil wire just pull the fuel pump relay or fuse, hurts a lot less than getting zapped by the coil.

Yeah, def something in case that ever happens again. I needed the engine off quickly and that's the first thing I thought of, I just used some pliers for that exact reason lol. Thank you!

I had this exact same thing happen to me years ago with an old Chevy pickup. Turned out to be wires at back of fuse panel under dash, that had rubbed thru the insulation and was feeding power to ignition circuit when key was off. Yours is likely to do with the ignition switch but the fuse panel is worth a look. Just unbolt from firewall and pull around to look see.

I'll take a peek. Thank you!

It’s easier to just paste the link, but add the hazard/turn signal switch to the list of things to check.

Cliff’s Notes version: the pins in the hazard button switch shifted and shorted battery voltage to the ignition circuit.

Electrical issue

I have a 98 tahoe 2wd. It has an electrical issue i can't seem to find. My right turn signal does not flash and my brake lights stay on when the key is on. I have replaced the brake light switch, flasher and even the rear brake light assemblies. What makes it more strange is that i can shut the...
