Hello,

This could be a problem with your vehicle's Crankshaft Position Sensor (CKP). Your vehicle's Power-train Control Module (PCM) uses the signal from the CKP to determine which spark to fire and when. Without this signal going to the PCM your vehicle will not run. I have included a few links below for you to go to:

I have also included in the diagrams down below the location of the CKP sensor on your vehicle. Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
