Would the crank shaft or cam shaft sensor keep the car from running? It starts and runs for like 5 seconds then it stops running I changed the fuel pump and also changed the fuel filter
Do you

Is there a security light? It may be preventing the car from running.

Cant. You need a shop to check it out. There are 2 wires in the lock cylinder that break. Common failure requires replacing the cylinder assembly and getting new keys. Have a shop check it and confirm.

I can give you a way to bypass the lock sensor if it happens again but for now try the relearn process.

PASSLOCK 10 MINUTE RELEARN

AUTO LEARN
Time required, approximately 10 minutes:

1. Insure that the battery is fully charged.
2. Use the scan tool in order to clear the DTCs.
3. Turn the ignition switch from the OFF position to the CRANK position attempting to start the vehicle. The vehicle will start and then stall.
4. Leave the ignition switch in the ON position while observing the security indicator.
5. When the security indicator turns off, which can take up to 10 minutes, turn the ignition switch off. Wait 10 seconds.
6. The BCM and the PCM will learn the new code on the next start attempt.

After further reviewing your system, bypass isn't really an option because you have PasskeyIII and not Passlock. If the relearn doesn't work, You will need a shop to resolve it for you as ASEmaster6371 advised
