Can't seem to figure out my problem every other cylinder not firing its been a headache so far ive seen where it could be the reluctor wheel backwards although mine wasn't removed so im lost have 12v to every coil just no fire signal from the pcm

You've seen where it could be the reluctor wheel backwards? That would be something to see. Where did you hear that?

Troberts56

Yes it was actually a thread on here that texas speed had commented on

So you just went out to start your daily driver one day and this happened?
Or is it a rebuild? New build? Swap? Factory vehicle with a factory harness? Swap with a swap harness?

It's not the everyday problem. Check the grounds.

Might be the PCM.

What is the vehicle model and year?

It's a 91 c1500 with a 5.3 swap custom harness built off of lt1 swap.com I've checked grounds even switched them around to reassure tested with a volt meter .08 ohms on all coil grounds and .05 and under on every other ground im gonna try another pcm but im still lost

Ok, so this has never ran or it was running fine and this problem happened?

Troberts56
