Hello, my name is XXXXX. XXXX likely you have a theft deterrent system that is malfunctioning. Your key has a small resistor built into it that the ignition lock cylinder "reads" before allowing vehicle to start. these cars are known for the small wires that run to ignition cylinder to break thus resulting in a no start condition
Here is a schematic to help you better understand what it is I am referring to.
how do i get to those wires to see if that is my issue..... i have the steering column torn apart but the part with the lock cylinder is enclosed with plastic all the way around it
Here is the remainder of ignition system diagram.
at the base of steering column, locate the 2 wires from ignition cylinder ppl/white and white/black. measure resistance with key in ignition and with key out. If no change in reading suspect broken wires. They usually break real close to ignition cylinder and are unrepairable, requiring new ignition cylinder
ok..... is there any way to bi-pass that system ?
the symptom that i had before the car wouldnt start is that i would turn the key and nothing would happen so i would turn it again and then it would start... i originally suspected starter soleniod so i replaced the starter......
it was just weird because the car started and ran monday night and then tuesday morning i come outside and there is nothing.....
If you can find out what the resitance pellet in your key is rated at it would be possible to fake out theft deterrent module by permanently installing properly rated resistor in between the ignition cylinder circuits.
the wire was probaly makeing intermittent contact and then broke all the way
Any gm dealer should be able to read your key and tell you what resistance it has
but you first need to verify that this is your problem
ok....... based on everything that i have already tried, i have pretty much ruled out everything except for this
after looking at diagram, there isn't much left, but I still like to confirm diagnosis before component replacement.
tomorrow i will check the resistance in those wires you listed and see what kind of readings i get and do a little bit of investigating
sounds good, good luck
thank you sir! i appreciate it
