Hey

I have a problem that I can't figure out. I can't get the car to turn off when the car is properly warmed up. There is a continuous power on, even I remove keys from ignition. Fuel pump gets power and battery, oil pressure and brake lights are on. The car shuts off when I remove a fuel pump relay or fuse, but dash warning lights stay on. Sometimes car won’t turn off, if negative lead is removed from battery. Last time I heard short buzz sound from fuel pump, when I switched lights on and off repeatedly.

So far, I have replaced
ignition switch
fuse box
fuel pump relay

Any idea what should I check next?

Finally I took my car to local Bosch Car Service and they found the problem in a less than three hours. Alternator b+ wire was rubbing igninition coil bypass wire, so circuit 15 was on all the time. Now I have new wire rerouted and problem solved.
