Hello,
This could be a problem with your vehicle's Crankshaft Position Sensor (CKP). Your vehicle's Power-train Control Module or "computer" uses the information of the CKP to determine the speed of the crankshaft and by this the rpm's of the engine. Without this information your vehicle will not start. I have included a couple of diagrams in the diagrams down below and a few links below:

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