Help Required - YB not start due to injectors not firing
Hi all,
Wondered if any has experienced an issue with injectors not firing?
Ill start from the beginning - my engine is freshly built all sensors all new apart from the 3 bar map sensor, ISCV and pf09 TPS
Also installed is a brand new CW Looms engine loom with integrated wasted spark.
All relays are powered - pump is priming and pumping while cranking. Also have spark but I removed the plugs and the bores are as dry as a bone.
We decided to put a feed directly over each injector for a few seconds - turned the key and it instantly came to life. So must be sparking and firing the correct side of the coil.
Ive put a meter across the phase and cps sensor with the following results:
CPS
657 ohms off trigger
612 ohms on trigger
Phase
714 ohms off trigger
670 odd ohms on trigger
Ive pinged all the earths and they are all good. Added new earth straps for piece of mind. Battery to chassis and battery to engine.
I don't have a set of NOIDs but I intend to order some tomorrow, but im 99.9% they are not getting the pulse from ECU.
Spec:
4x4 engine loom - including wasted spark NEW
L8 ECU Pectel board & Wasted spark driver
PF09 USED
ISCV USED
3 bar Map USED
New phase
New ACT
New ECT
New Temp
New CPS
New twin air injectors
Any advise would be greatly received.
Thanks,
Chris

Hi,
Have you got the phase sensor plugs and knock sensor plugs wrong way about?, also is the phase sensor plug inside dizzy the right way about, as that will cause issues with injectors
Cheers
