Well, I had a little tinker today...
Diagnostics. After some temporary repairs, I have these functioning. It appears the injectors aren't operating.
Codes. 4411, 4412, 4413, 4414.
On the subject of diagnostics; are there any differences between the PT and ABH ECUs? The ABH setup doesn't seem to respond to the ClosedThrottle trigger. It could be that this is a part of my problem.
So. Engine still not currently running.
