No buzz to driver bank
Last time I started this truck had one bad cylinder. It ran just one lacking compression.
put a used motor in it that came a video. Good source of parts. We went ahead put new wiring harness and valve cover gaskets bc the existing just so old worn out. And, not knowing the shape of the injector - swapped in all the injectors from my motor. I shimmed all my injectors which had produced really solid results for me.
I swapped idm w another truck in my yard that runs fine. The suspect idm buzzes fine other truck.
ohm test all comes back to .8. Very little resistance. I would think good clear conductivity.
what an I missing? Can a pcm cause half not to buzz?

but on buzz, I was getting high to low size short on 2 6 8. And I was getting possible short codes on icp and oil temp sensor. I deleted the turbo stand and the air box is out so those coding. Those will code.
but, I wondered about the pcm bc of the icp and oil temp sensor codes. Haven’t cranked it to see if I’m getting psi readings but working thru electrical gremlins. But before I buzz tested it due to no smoke no start, I was getting good oil pressure reading. So I’ve ignored it to now

Update
Icp was bad was giving high readings. Swapped in a known good one and I’m only getting about 200 psi and ipr 66-67%. I’m pretty sure is a non start due to the IPR. We’ll try that in the morning figure out what’s up w these injectors in due course.

Anybody got some ideas
Cannot get buzz to drivers bank. Tried just about everything
New valve cover gaskets,
new wiring harness,
ohm all coming back w 2.6, 2.7 ohms on each channel.
Swapped in known good pcm,
known good idm and
known good cluster.
only symptoms I can’t seem to resolve as far as codes and w trying other sensors is oil temp sensor is reading 212 no matter how many I try. Def a problem there. I know the idm is in the signal return- what sensor could duck it up like that?

Well, ya just never know wtf is gonna happen when you buy parts these days. Ordered a new uvch and checking the eot issues - the wiring is wrong. The eot wiring comes back to the wrong pins in the uvch connector- wrong damn pins so it’s not gonna be right.
still not the issue w my drivers bank. Gonna try to shim the injectors and see if maybe the solenoids are too close to the poppets. I don’t know what else to try. I’ve got two of these trucks two mos off the same assembly line - have swapped over just about every damn part there is and still cannot get the drivers bank to buzz at all.
driving me insane.

Swap solenoids left and right. Just a couple is sufficient. If the problem continues it ain't the injectors, it's the wiring.

Check the resistance to ground on injector wiring. It sounds like a few of you injectors have a short to ground in the wiring.
Shimming them I don’t think will help anything with a buzz test.
I would do the check to ground as mentioned then swap the wiring harness back to the original. My guess is there’s something wrong in the new harness causing a short.

I checked all 17 or so leads at the idm harness for short to ground. The only lead showing ground is the ground lead. It doesn’t make a damn bit of sense.
Passenger side is good and strong. drivers side completely dead. In the past, just to check injectors, I’ve plugged them in and laid them in too the motor to make sure they were buzzing. I have several of these motors - always something. But, never to this strange.
usually comes back to idm or pcm or bad wire. Something. Usually you catch it w a multimeter.
does anybody know if there is a comm error that it defaults to the passenger side? Is it only buzzing the passenger side due to a fault I’m not familiar with?

Let me say I don’t have any codes to suggest any such error. Only significant codes I have is 2, 6 and 8 high to low side open. 4 doesn’t not buzz that I can hear or feel but for some reason it doesn’t code.

Personally, I would put the original wire harness on it for a test. I try to start simple with the last thing touched or newly replaced.

for your peace of mind,
send the IDM to

got that info from

PCM and IDM showed up from Diesel Tech of Chattanooga.
I am extremely impressed with their work. The performance tune they flashed to my PCM paired with the HVHC IDM seriously woke this truck up. Ran Forscan after I had the truck running for a bit and I have no issues now.

It’s not the idm. I have two trucks 2 mos apart on the same line. Swapped every back and forth and the second truck buzzes fine
idm operation. I’ve problem run 100 buzz tests - dream about the Mfers in my sleep. 1 and 5 are loudest. 1 and 5 are supposed to be the synchronization cylinders. Maybe neither bank is firing and it’s just buzzing 1 and 5? Does that cue anybody up? Make sense to anyone please?

Victory!
Finally got shin kits in. If you run into injector issues and just can’t figure them it WTH is going on bc everything ohms good and everything has connectivity - shim your injectors.
I had recurring 2-6-8 injector codes. Buzzed passenger side but it wasn’t really buzzing in passenger side. Finally sat down last night w 8 known good injectors but not shim’d. Sat around 4 hrs and shimmed them all. Put them in this am - no codes. All buzz.
**** ton of wasted time
