Yea mate it's a Vmac1 has the 2 separate modules and the year is a 93 build

E7 ecu came back from suspension place with codes 2-2 2-4 and 3-3 I think they line bored the front hangers without disconnecting the batterys Now I've test all the wiring harness for a shorts to ground and to each other in which I found at the coolant temp sensor the was 4.5v on both wires so I unplug the fic module and the 4.5 voltage went away on the ground wire So we swapped the fic module with a known good unit out of one of our other trucks and that seem to fix the problem however we left it plugged it and went away for work we came back to it the truck had the same faults and we think its fried a second module The truck won't start unless the throttle is held flat and if you drive the truck it sputters around 1200rpm on deceleration like it loses RPM signal or something Any help would be much appreciated also we're from Australia 🇦🇺
