Hello, my name is Bobby. Thank you for the question. I am sorry that no one has gotten to you sooner. Are you still available or me to assist you with this?
Thank you. Lets see what we can do. Can you tell me if the engine died while driving or did it just refuse to start? Is the security light on when cranking the engine?
Did you actually test the fuel pressure? Did you try adding some fuel directly into the engine to see if it will start?
You may want to do a compression test to make sure that the valve timing did not jump. What I am suspecting though is a security system issue. If the security light is on while cranking the engine then it is the problem and is keeping it from starting. If it is not on and if compression is fine then it may have ignition timing that is off due to a failing crank sensor. A new one would need to be installed and then a relearn procedure would need to be done with a scan tool that has the right capability.
The rotor should only go on in one direction. The way that I would check fuel being fuel related is by adding starting fluid straight into the engine where the air filter tube connects. You would need a higher end can tool like a TECHII to do the relearn if it was the crank sensor.
You would either get this from the ignition timing not being correct or from an internal engine issue causing the valve timing to be incorrect.
