if it has data stream, then yes it should.Tim
So with the new ecm, it says it has sync? but before it had no sync?
this car has a auto shut down relay.....what is in correspondence to this? wires are checking to have good resistance....is there something with the alarm...... the car was ran hot and it shut down on customer...now it wont run....
If you have power at the coils, then the auto shut down is good, you have new sensors and the wires are good, if you dont have crank and cam signals, then this leaves the ecm, did you replace it with new or used? how did you program it?
