Hello,

This could be a problem with an open or unwanted resistance in your vehicle's Crankshaft Position Sensor[CKP] electrical connector or wires going to your vehicle's Power-train Control Module[PCM]. In the diagrams down below I have included the wiring diagrams for your vehicle's power-train management circuits. I have highlighted the CKP wiring for you. I have also included guides on how to find opens and unwanted resistance in an automotive electrical circuit using voltage drop. You will need to use a Digital Multi-meter [DMM] to go through these guides, so here is a link below explaining how to use one, if needed:

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

Thanks,
Alex
