Nissan frontier no injector pulse was created by mace93
Hi guys, i have a nissan frontier 2002 3.3 v6.
I got a intermittent crank no start issue.
Sometime the truck won't start because it loses injector pulses. I have power to the injectors but not ground when cranking.
I thought it can be crank or cam sensor issue, but i get rpm signal and spark(tested with started fluid)
What it can be guys? i am lost.
please help me. thanks

Moved this to the Repair section. ;)

No trouble codes stored? I figure you'd have said so if there were, but I gotta ask. :cheer:

probably an immobilizer issue. if you have cam and crank signals... maybe when it happens again try a different key

i don't think. the key is a simple one, just metal no chip on it.

All 6 don't fire? Verify computer's powers and grounds.

Do you have a scope to test the cam and crank sensor? I can't remember off the top of my head but does this have a distributor? Had one with bad random misfires affecting the injectors and it was dust blocking the holes for the optical sensor inside the distributor
