I was thinking the same way. I did the wires one at a time. But with my luck on this thing who knows.

When the connector burnt out it took the pin in the gasket and the plug ins inside and out so I had to replace the under cover harness, the gasket and the outer pigtail

What you can do to narrow it down is to start it up and then unplug one plug at a time to see which one doesn't make a difference. Just be really careful. Those injectors run on 110 volts. The plug that makes the least difference is the one that contains the issue.

That makes sense, be like pulling the plug wires on a spark ignition engine.

I'm done for the night. I'll be back when I have more to report.

I took the truck back to the dealer today and showed them it ran without spending over 1K on injectors. They had no answer as to why they couldn't find the cps issue. I did have them run a diagnostic on it again(on their dime) looking for the cyl it's missing on. They said cyl 2 and 6 was bad and they were again blaming injectors.

I brought it home again and I will be looking to verify the missing cyl.

I did find it when it's missing it blows light colored smoke, I assume unburnt fuel. And it would come and go as it would run close to right and get bad again.

Does it miss like that all the time or just intermittently? And it didn't miss at all before all of this started (when it died originally)?

The miss and smoke comes and goes and no it ran great before it died. It's like a bunch of things happened all at once. I don't get it!

I'll have to check it. I'm also going to take my oil pressure gauge from the right bank and put over on the left and see if it's steady.

As a side note, I did find some injectors that a guy had rebuilt and then changed his mind and put in bigger ones. he says they are Rosewood rebuilds. Deal was too good to pass up so I grabbed em.

Sweet! What are the specs on them? Stock rebuilds or are they a lot bigger? If they're much bigger, you may need to do some supporting modifications, but it just depends on what they are. Rosewoods are some good stuff. Jim knows what he's doing with these things.

He didn't specify but since he said he went bigger I assume they are stock. And stock is all I need. with my chip truck has all I want. When it runs anyway.

Have you ran the living crap out of it yet? It takes a good beating to get all the air out of the oil rails.

WOW Since there was nothing wrong mechanically before. Maybe I'll put insurance back on and just drive it. I still want to check the pressure on that side first. Just need time to work on it.

I went out for a drive again. This time I noticed whenever it started missing there would be some kind of flutter in the intake. Got it back in the shop, took the intake "Y" off so I could hear each side. When it missed the right bank has pretty loud popping noise. Now I'm thinking an intake valve is seating and unseating, causing the intermittent miss. I did narrow it down to the second cyl on that bank. When it misses that one does nothing and when it runs good that one definitely loses power when injector is unplugged.
