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 engine rotation for rpm's and misfire monitor. If it isn't getting a signal from the CKP then it won't know that the engine is cranking. I have included diagrams for you in the diagrams down below as well as a few links for you to go to down below:

Please go through the guides and get back to us with what you are able to find out please.

Thanks,
