On a few occasions when I went to start my truck I would turn the key forward and no idiot light would come on and the truck wouldnt start ( no power ). After a few minutes of wiggling my key in the ignition lock cylinder and wiggling the steering wheel my idiot light would come back on and my truck would start.
my truck is currently not starting and after alot of wiggling I get no idiot light. The battery is charged, my interior light works and my headlights come on. When my truck does this I keep the key turned forward, I get no power at the radio, the hazzard lights and signal lights and wipers dont get power either. I chaned the ignition lock cylinder and the ignition switch as well but I still get no power when I turn the key. Both ways. When I turn the key back to accessory nothing gets power. PLEASE HELP. Thank you for your time

Chances are the actual ignition switch (on the steering column not the tumbler) is out of adjustment or is bad. I would have that checked.

Thank you for your response.I have changed the ignition switch on the steering column as well as the lock cylinder with no luck.I used a 12v test light on all the wires going to the ignition switch, none were live. The wiring diagram in my repair manual states one wire is always live but it doesnt say which
unless I recieved a faulty switch from the parts store the problem must be elsewhere. Thank you for your time and effort

You need to track down where the power should be coming from. Chances are there is a broken wire.

Thank you very much for your help. The problem turned out to be a loose wire in the engine compartment.I turned on my wipers and started wiggling wires under the hood.I was very happy when I discovered a loose connection which when shaken powered up my ignition switch. Unfortunately I checked the wiring after dropping the steering column and changing the ignition switch and lock cylinder. Hopefully someone in the same predicament will read this before taking apart their steering column. Lol. THANKS AGAIN. YOU GUYS ROCK
