Will not start, but will run with starting fluid?

Hello,

Have you carried out a CAN scan to check if any relevant fault codes are set?

This would be the easiest starting point. Once done please post any fault codes here for further evaluation.

Also, check to see if, while cranking, there is any movement of the tachometer.
This is a basic check to see if the PCM is getting a rpm signal.
Without an RPM signal the ignition coils nor the fuel injectors will be triggered.
This RPM signal is created by the crankshaft position sensor.

I would suggest first carrying out a CAN scan before you start replacing any parts.

Cheers, Boris
