    Still having trouble, need recomendations

    Contacted GOECM about the work they did on my ecm. They asked me to bring it back in so a senior technician can verify the work that was done. I asked if the ecm would have a problem operating LLY injector instead of LBZ injectors. They said the LLY injector take more voltage. And asked if the...

    Never mind the green highlighting I snagged these pinout lists from another thread. The excel file I put together to help me verify the injector circuits in the ECM plug. For my next test.

    Holy smokes, I have heard misery loves company tlbut that is just not a good common experience to deal with. I am planning to use some deoxit5 that just came In via Amazon. Then run a continuity check from the plugs at the injector to the connection at the ECM. if that all checks out and I am...

    Thanks, luckily my brother in law and my closest friend re defines hard headedness and will not give up. I know it takes patience and practicality. Methodic step by step. I appreciate the suggestions.

    Bad luck, re installed the ecm, truck doing exactly the same. Runs well at idle. Le it idle for about 15 min. Went to close the hood. As soon as the hood latched, the rattle started. I have dumped over 4500 bucks into this problem and it runs no better than it did. This is feeling pretty...

    Previously yes. I backed out the tune to stock after swapping out the injectors. I am wondering if the stock tune could have gotten botched some how. But I doubt it be cause on cold start it runs great. Just after the truck warms up or starts jossleing around it goes bad.

    Re installed the "rebuilt ecm" absolutely no difference in the truck. Same issues. Runs great for about 15 min then starts running like crap. I will try to verify the wiring between the bail connector and the ecm tomorrow. Nearly at the end of my rope

    I have already replaced the injectors with LBZ versions. Stock bosch from LDS. Replaced the engine harness (also from LDS). The ECM was repaired, and I will be installing it in about an hour. The truck ran perfectly for about 20-30 minutes after the Injector replacement, then it would go into...

    LDS called to confirm they received my core exchanges on the injectors. They have been aware of the issues we have been experiencing and offering support where they could. They also though I might like to know that the oem injectors I sent them from my truck were LLY injectors. They seem to...

    GoECM called today and explained that some caps were out and something to do with the battery contacts were bad as well. In an case they were able to repair the ECM and it is ready to go. As soon as I can get there after the huricanne. I will update.

    We checked them thoroughly and used contact cleaner to ensure a clean connection. That was the low hanging fruit we were hoping to find early, without success. The engine harness has been replaced and the problem persists. If the ECM shows no issues we can check resistance from the ECM plug thru...

    We took pictures of the bail connectors and ohm'd out the circuits for the injectors found the comons and the dedicated lines. If you look close at the pictures we wrote the cylinder designations on them. The small bail connector is for one bank, the larger one is for the other bank. We ohm'd...

    Thanks for the support, I had a sit down with the secretary at the shop. Every question she would go to the back and ask then come back. Took much longer than necessary, but she relayed the information and indicated that they have s÷n this before and that it could be possibly a bad "cap", which...

    He's, we put brand new Bosch injectors in the truck, then we replaced the engine wiring harness, still the same. So we swapped #3 and #1 injectors as they are on different banks. (Same side different banks). And number 1 & 4 were still showing issues. So we identified the curcuits and ohm'd them...

    Thanks. For the trouble shooting guide. Good to know we did our due diligence. I contacted a local ecm company this morning here in Houston and they willvtest mine for 100$ and rebuilditbif required. So at least I can check that component off the list. Appreciate the support. BTW. The pigtails...

    These are the balance rates for the injectors after the truck warms up. 15-20 min at idle. They are all within spec and look great beforehand.

    The codes are not consistent. But generally are 0201 0204 and 2146. There have been times when I got 2149 as well. But only once or twice. I think the codes are very vague and not as direct as I had hoped for.

    2006 lbz with 245k miles 4x4, lifted 6", PPE tuner, cat delete. Started getting injector codes. Replaced Injectors with new stock injectors. At first start up ran like new for 30 min. Then clattering. Clear the codes and again the truck ran like new for about 10 miles then the process continued...
