No start
I have an L77, a 6L80e, ECM and X1 and X2 connectors, all from the same vehicle, a 2011 VE Commodore, going into a kit car. Vats disabled and Mafless. No BCM. Auto sparky disabled Vats, tested ECM, and it started another auto vehicle.
I cannot get any signals from the ECM despite proper feeds to it, grounding and trans in Park. So no DLC readings and no fuel pump priming via pin 50. Battery and ignition feeds to ECM currently 12.6v. No crank when starter relay is wired via pin 52 to ECM, and grounded to chassis, but will crank but not start when starter relay is wired direct to column starter wire. Fuel pump operates but only with direct ignition feed to its relay.
Another auto sparky recently tested all wiring, injectors and coils, found no faults, but could not get start. New crankshaft and camshaft sensors, and new internal mode switch in trans. Auto trans 16 pin plug wired up, including battery, ignition and accessory feeds. Wire run between pin 3 on 16 pin plug to X1-1 on ECM. Presently reads 11.6v.
Any further wiring needed? Would wiring up a BCM make any difference?
