Weird situation yesterday. Stopped for diesel fuel and engine did not turn off even with the ignition key turned off and removed. Tried it several times. Fueled up, went inside and paid, came out and engine was off with the keys in my pocket. Prayed a bit, started right up and got to Branson and it shut off normally. Looked underneath at the ignition switch wiring, all looks secure.

Replace ignition switch is my thinking...but I am asking all out there if you have experienced this?

How would I shut it off if this happens again? Turn off the main electrical cutoff in the engine battery compartment?

WOW, that’s no fun. I’d probably start with the ignition switch. I’ll be waiting to see what responses you get.

The emergency engine shut off in the in the engine compartment could be used to shut down the motor. These intermittent problems are the hardest to find. Good luck.

There's a relay in the electronics bay below the drivers seat. Follow the large red cable to find it. I would guess it may be sticking and need replacement as they are sealed.

I agree with Bill on how hard it is to find these intermittent problems. Not sure in your model how easy or hard it is to get to the switch but i would start there. I believe in the on position voltage is sent to the fuel solenoid directly from the ignition switch.

Good luck and let us know what you find.

It wasn’t the ignition switch. My daytime running lights quit working and the shop that did some trouble shooting in Oklahoma, also did some rewriting for some reason (found this out later). I found that if I turn the key off and I turn on my bright lights, the engine stops. This does not happen when driving thank goodness. Asking that shop to tell me what they required and I will undo it. We are not scheduled to be back there until next fall at the earliest. My DRL system is all screwed up now. Worked fine in the shop and when i picked it up. All the symptoms with the DRL show up when in Drive, and the Parking Brake OFF. I HATE electrical problems!!

I had the same on my 04 Dynasty...started out being slow to shut off, but finally it would not shut off even disconnecting the batteries...alternator still supplying power. My engine previously shut down while on the road...found the blown fuse on the remote start board in the back so by pulling it the engine shut down. Traced the power back to the Bird board and a shorted diode. Was able to replace the diode solving the problem. My problem had nothing to do with the key switch but worth knowing which wire looses power when you turn the key off so when it happens again you can check if the key is working.

I would check the ignition solenoid the next time you can't shut down. After turning off the key and the engine is still running, check the voltage at the coil windings for the solenoid. If there is still 12 volts on the coil then it sounds like your repair people somehow added a 12 volt supply to that circuit. Since you have found a weird way to shut down I doubt it is a faulty ignition solenoid.
