Customer Question
Why are cylinders 1,3,5 firing...
Why are cylinders 1,3,5 firing on my vy commodore 3.8. Ive checked everything as i am mechanically minded.
Ive checked the dfi, coil packs, spark plugs, fule pressure regulator, power to the injector plugs, sapped the injectors from 1.3.5 with the passenger side 2.4.6 same result. Swaped out my relays and checked all my fuses. Swapped my computer and bcm module with another 6v auto vy computer. swapped my o2 sensors and throttle body.
If any one can help it would be appreciated

Hello there,

The whole of bank 1, cylinders 1,3,5 are not firing, correct?

Are your leads routed correctly, 1and 4, 2 and 5, 3 and 6?

Have you verified injector pulse at each injector with a noid light?

Have you done a compression test on all 6 cylinders with all spark plugs out?

Gary
