Crank up and went to move it shut off and now will not crank. Getting fuel to fuel rail. Fuel pump is running. Tried the ten minute security reset. Tried the turn switch five times reset. Pulled the crank shaft position sensor and bench tested. It failed bought a new one and installed. Still not working. Switched fuses around. Still nothing. No security lights. Tried to crank with just key no fob attached. Nothing. Help please.

Hello,

Okay, so you are getting fuel to the fuel rail. Let's check to see if you are getting spark. Here is a link for you to go to to see if your vehicle is getting spark or not:

Hello again,

Okay, you guys are getting fuel, getting spark. Have you guys check the Camshaft Position Sensor (CMP)? I have included a description of it's operation in the diagrams down below. Your vehicle's fuel injectors might not be getting turned on by the Power-train Control Module (PCM). Please go through this guide, check the CMP and get back to us with what you find out.

Thanks,
Alex
