Hello,

This could be a problem with your vehicle's Crankshaft Position Sensor [CKP] which is used by your vehicle's PCM to synchronize the fuel injectors and the spark timing. In the diagrams down below I have included the wiring diagram of your vehicle's starting circuit along with instructions for the removal and installation of the CKP sensor. Here is a generic link to a guide explaining how to replace a CKP sensor down below:

Please go through these guides and get back to us with how everything turns out. We can go from there if necessary.

Thanks,
Alex
