Vn 304 half injector pulse

Post by Snappy »

Hi all I have a bit of a problem with a Holden 304 from a vn commodore that I'm putting in my gq patrol
Now I have it running but only on 4 cylinders
I'm not getting injector pulse to the RH bank of injectors
The LH bank are all pulsing fine.
So far I have checked
Power to injectors with ignition on an while cranking - ok
Continuity between injectors an ecu pins D15 an D16 - ok
Continuity between ecu earths an engine block - ok
Have tryed 4 ecus now with the same memcal witch has had a 276 cam tune put on by a fellow member
Is it possible the memcal is at fault ? I just don't have another to try
Am at a loss of what it could be does anyone have any ideas or other tests I could do ?
Thanks

Sounds like 4 stuck injectors have you cranked it with the fuel rail lifted up so the injectors are out to see if it sprays
If Its Got Gas Or Ass Count Me In.if it cant be fixed with a hammer you have an electrical problem

If you have a noid light you can see if they are pulsing at the plugs test light probably not.is it a stock uncut harness there was a join between d15 and 16 in the harness itself I think
