    No start, no codes, this truck is killing me!

    It's making about 60psi of oil pressure when cranking. A little shot of starting fluid got it to stumble, but not enough to actually fire. No smoke out the pipe, and no smell of diesel either. Would the injection pump being bad cause it to leak the pressure out the return line?

    No start, no codes, this truck is killing me!

    So last week my truck let me stranded, no start, no codes... I only had my torque app available, so I couldn't do much troubleshooting. After the 60 mile tow, I hooked up the tech2 it showed only around 190psi of fuel pressure while cranking. Doing a bottle test with the hand pump the fuel...

    Engine / Allison transmission alignment

    That was my thoughts as well. I found a PDF, that looks like it's from GM, about replacing the LB7 and it said to remove the motor mounts. I appreciate the help, guys.

    Engine / Allison transmission alignment

    Thanks! I pulled it out again, checked the converter and it seemed seated. This time I took off the motor mounts and was able to get them to mate. Thanks for the reply! Now onto final assembly

    Engine / Allison transmission alignment

    I'm mid-way through getting my Duramax back going again. Pulled the old motor, swapped out wiring harness, intake manifold, and all the other fun bits from my '01 lb7 to the new '03 lb7. The engine is in the truck, but for the life of me, I can't get the transmission to mate with it correctly...

    Transplant '03 engine to a '01 truck

    Got the old motor out, and am working though getting things swapped over to the new one. What about the injection pump?

    Thanks, Guys. Sounds like I'll need to plan for a few days of swapping everything. I appreciate the help!

    Transplant '03 engine to a '01 truck

    Thanks, the forum move makes sense. The '01 block is bad, I should have mentioned that in the original post. What about the wiring harness? Would it be ok to use the '03, or do I need to use the '01 as well?

    Transplant '03 engine to a '01 truck

    Hi All, I purchased a new (to me) '03 running LB7 engine to put into my '01 truck. I've been researching but didn't find many answers to the differences between LB7 production years. I read somewhere about the '03 had a new data bus system, and some of the sensors reported to the bus...
