Ok, testing results for today:
1. Switched plug wires. Switched 1 that 1 knew was firing to the 1 that was cold. No change.
2. switched coil pack. same thing, switched for 1 that was firing. No change.
3. checked spark. good spark.
so, at this point I pulled the plugs from the 2 that were not firing. They were dry. I thought maybe the injectors were bad.
4. put a noid light on the 2 bad ones. They onyl lit up 3-4 times. Put the noid light on 2 good ones & they were kept lighting up regular.
Why would the injectors pulse just a few times?

They wiring to both injectors are good. I checked continuity to the PCM & that was good. I also checked the power to the injector & it was 12v. I swapped an injectoer that was woking with 1 that was pulsing & that made no difference
So, I think I have ruled out the injectors & the wiring. What does that leave? I think that can only leave the PCM, but I can hardly believe that I have 2 bad PCM's.
Any other ideas?
Thanks

What year pcm are you using?? Post 98?? as in 2000-2002?? or 98-99? would make a difference.

Where do you live?? I have a PCM that I'm going to use for my Nitrous that has an NA tune in it that we could probably use to get it fired. Obviously my engine setup is different than yours but it might get you an answer to the PCM question of bad pcm or tune issue. Let me know.

Whats the cranking compression on all cyl's? Im late into the game on your problem, give me some details. used ls1 swap, rebuilt ls1, has it ever ran good?
Also, what did the injectors ohm out at? You never posted your results. In earlier posts, you said you had injector pulse with a noid light for a few rotations and then nothing. Is it still doing the same thing? Do you have spark on the dead cyl's all the time?

I'll have to check the ohm's again, but I think they were in the correct range. (I'll check again this weekend).
I have not done cranking compression.
yes, those 2 injectors still have intermittent pulse seen w/ noid.
Yes, good spark on the 2 irregular pulsing cyl's.
Thanks for joining the party & thanks for the help.

Saw the post and I posted a response as well. My connectors aren't green and blue....they are red and blue. I believe pin placement and corresponding wires may be an issue with this.

This is very frustrating. Being so close & yet so far from getting this thing driving.
I am trying to see if Jon from PSI will trade out PCM's.

Have tried to a little bit....breaking is very hard on it. I am walking more without the boot and a single crutch BUT I still can't put full weight on the outside portion of my foot nor can I twist it at all. Must be very deliberate(sp)in my steps and have been banned from helping Cyndi in the yard due to turning it again.
VERY SLOW PROCESS FOR WHICH I HAVE NO PATIENCE!!
How's the New Job??
