Hey guys,
I've swapped a gen3 coyote drivetrain along with the fuse box, wiring and most modules (ECM, BCM, BCMB, GWM, and some others) but it won't start. Accessory power will turn on as usual, however the start/stop button green light flashes rapidly instead of staying solid green as usual. I've looked in the owner's manual as well as FSM for what this means but can't find a definitive answer. Does anyone know? The fuel pump also does not cycle when the accessory power is turned on so I suspect the engine immobilizer (if so equipped) is triggered and preventing it from starting. I've also jumpered the starter relay and it will crank over but will not catch and start. Doesn't even sound close, as if its getting no fuel. The fuel pump does power up when jumpering the starter relay, but only gets about 3 volts.
I have a number of DTC's, but none are PATS related and none that I can see that would obviously prevent the car from starting. So does anyone know about the existence of this engine immobilizer and can tell me more about it? If it is activated does it throw a DTC?
Does anyone know of any particular PID's I should investigate/monitor for further troubleshooting?
Thanks in advance.
