Only three pistons firing

[YourmamaISSOL]

ok I have a 94, 4.0 and have just done a manual swap.

the three pistons are firing on the pass side, but the driver side is not firing at all any suggestions?


I have spark to all 6, I have swapped the computer and think I have the wiring correct. any help would be appreciated.

Thanks
Gary

Pistons don't fire. If you have spark to all 6 plugs, then the injectors aren't firing, or are firing at the wrong time. I'd double check the coilpack wiring, and the injectors.
