If you have even a Basic Scanner.... or can pick one up from Autozone... Knowing the Code(s) History would be a big help. As good as many of our Members here are with figuring out things... I doubt that we have any Clairvoyants among us. Have you done any very recent repairs or changed anything from being "Stock As A Clock" as per the Radio, HIB, etc...?
Here are some Very Basic Wiring Diagrams of the Starter Circuit...
please take note of the divergence (Gray Wire) for the Security and the fact that this Class 2 Signal Wire goes to the PCM and is necessary to give permission for the Fuel Pump to engage. If you have had to work around the Ignition Switch at all recently... something may have gotten disturbed in that area.
Try moving the Steering Column Height Adjustment throughout its full range and... Very Carefully remove the Ignition Key...and insert/remove it in the Key-Lock Cylinder a few times... then try again to get the vehicle to start. If it does.... move the Steering Wheel up and down...Gently...and see if the engine cuts off. Does anybody else drive this vehicle... and what is your present mileage?
Tell us about anything else that has gone sideways with this vehicle to update other possible related issues. You will need a decent OBD2 Code Reader to help us out here:
