Turn the key and no engine crank. I can here the fuel pump working but thats all.
In the middle of nowhere all the lights on the dash go on and the car just turns off,as if I've turned the key to the left,and shut it off,I let up on the accelerator,and it usually,the panel goes back to normal,and the truck is back.
I can turn my ignition switch to the on position and no lights come on, and then I let the truck sit for a couple of minutes and the lights pop on and then I can start the truck.
my truck turned on by itself, no keys, and drove itself into my friends garage door =/ wtf

98' s10 2.2. Very intermittent problem for a couple of years now. Checked everything. Grounds, replaced the major grounds, battery, checked for shorts, blown fuses etc. It makes perfect scense that my truck loses all power and throws a light. What turns your vehicle on and off? The switch. Narrowed it down to this. Even the techs at the dealer said my ignition had a lot of slop in it. I will be replacing my switch here next weekend.
Abs light comes on and ac blower motor stops.
Traced it down to a bad contact on the ignition switch
