So should I just buy a whole new ignition switch and try that? And what could be out of alignment? I cannot read the schematic the writing is too small. Any chance you could find a larger one? I blew it up but still could not read it. And alright, I am in the garage doing it now. Putting everything back to stock.

That is the largest schematic I have and cannot get it bigger. It sounds like a bad switch to me based on how you said it was working.

Okay I will try and blow that up and read it. I will try replacing the ignition too. Also, I unplugged the BCM and it stopped the headlight flashing. You think that could be bad once again? And as far as replacing the ignition, it is the wires that do not have juice to them. Not sure if that is switch flaw or something to do with one of the computers or something. I want to take it to a mechanic, but do not want to pay out of another grand. So frustrating.

There should be at least one wire that is always hot to the ignition. If you do not have that, the switch may be fine.

My car will not start. All the lights come on and the radio. The security, low fuel, and battery lights flash on and off on order.

Hi and thanks for using 2CarPros.com.

It sounds like a problem with the anti-theft. Try this and let me know what happens. Turn the key to the run position and allow the vehicle to sit like that for approximately ten minutes or until the anti theft light turns off. If that happens, see if the car will then start.

Additionally, read through this link. It discusses common, easy to fix, no start issues.

Let me know what you find,
