Simon Posted June 7, 2012 Report Share Posted June 7, 2012 Are you measuring this voltage with the ECU connected and with trigger pullups turned on? Quote Link to comment Share on other sites More sharing options...
koo Posted June 10, 2012 Author Report Share Posted June 10, 2012 Yes the pullups are on. Does anyone have a wiring diagram for the holden V6 crank sensor? We have now injector pulse and spark but.. one pair of coils are not firing when cranking but they do fire when using the ecu ignition test..? The CDI is wired as wasted spark and cylinders 1+4 is the one driver thats not working. If the CDIs driver was damaged would it still fire using the test? I wouldnt think so? We have swapped coil plugs to rule out coils, leads and plugs, they are all working. Quote Link to comment Share on other sites More sharing options...
Simon Posted June 10, 2012 Report Share Posted June 10, 2012 What trigger mode are you currently running? Trigger one should be wired to the 18 tooth pick up and trigger 2 to the 3 tooth. Quote Link to comment Share on other sites More sharing options...
koo Posted June 11, 2012 Author Report Share Posted June 11, 2012 Is that for sequential injection? Or batch fire? Will the engine run in sequential using the 3x chopper on the crankshaft rather than the cam sensor? Or must l use the cam sensor. The car is configured to run in sequential.

Simon Posted June 13, 2012 Report Share Posted June 13, 2012 For sequential you will need the cam sensor and the 18 tooth crank. Run this in multi tooth mode. Quote Link to comment Share on other sites More sharing options...
