Greg, FYI, looks like my mechanic diagnosed my issue to be a bad ECU for me. All fuel relays, fuel pump, etc. work. Fuel rail has fuel in it. The injectors just don't squirt. He can't communicate with the ECU via the OBD2 port either. Lastly, when trying to start the car, the Check Engine Light does NOT even turn on. The CEL, along with the other lights, usually turn on when you start the engine. So maybe you have the same issue?
