New engine, will not start. Cal installed tune.
I'm following factory service manual "Engine cranks but won't start", step-by-step.
- Verified injector test light is functional.
- Fuel injector test light plugged into fuel injector harness and it does not blink during cranking
- I have 12V at the pink/black wire coil connector terminal "P"
- Coil connector removed, injector light plugged in, key-on, applied/touched 12V to coil connector terminal "C" and got no injector light.
- Circuit 430 is fine, I did a continuity check from the coil connector to the ECM connector and its Ok.
- I checked the voltage at ECU connector B5 and get 4.51V with key-on, which is within spec.
So according to the factory manual the ECU injector driver circuit is bad, anyone else run into this problem with Casper's box and/or FAST XFI?
