A month ago I was not able to get my 1994 Landcruiser to turn off. As soon as I turn the ignition to the OFF position, I can hear it cracking to start up again. I then turn the key to ON position and it fires right back up. No problem starting itself up. I have been trying to find other views and what other people are having problems with and all have been about their cars not starting. Mine had to be the one that just will not die! Everyone joke around that it was possessed. I just let it run and then drive around the block and was able to turn it off. It has not happen again since then but all of a sudden today, the check engine light came on while I was driving and I was not able to accelerate. I pull over to see what was going on and try to shut off the engine but it would not let me turn it off. The truck keeps on trying to start itself even through it was already running. Then all of the lights flashed on the dash board and then I smell something burning and then it shut off by itself. I was afraid to turn it back on and not be able to shut if off so I just had it towed back home. Need some advice on what the problem can be. Please help!
