    Rear Seat lift to accommodate sub box??

    Kit? Just weld two 1”1/2 pieces of angle iron together. You can use a pac adapter that plugs into the head unit to add rca and remote wire. Does it have bose? If so you can just tap the low level wires coming out of the head unit.

    Major LB7 problems -- need help

    Your injectors could be bad again, your CP3 could be weak. Wastegate could be broken or malfunctioning. If it was your exhaust gaskets you would hear a screeching sound under acceleration unless your exhaust leak is huge.

    LLY new engine won’t start.

    Well, I admitted defeat and dropped it off at the dealer. We’ll see what they figure out.

    I’m leaning towards that. Ground is good. Swapped in a working crank sensor. Going to swap the cam sensor.

    The injectors have been in the previous motor and it’s tuned for them. Coolant temp sensor is plugged in and reading.

    The factory filter head it’s gone. It has a fass with a nicktane added. Air was bleed there and at the fuel pressure sensor because I forgot to tighten it :rofl:

    Swapped the crank sensor already. I believe the cam sensor would still let it start it would just be extended cranking. I’ll have to double check that but I’ll swap it out anyway.

    Yes my LMM doesn’t have glow plugs but it’s 16.5:1 I’ll have to double check but I believe this motor is the same. I’m in California so it was around 70*

    Actual is 7k. I got ghetto and sprayed starting fluid. It runs on that. If I try and start the truck after it runs out of starting fluid it does fire and die. Seems like something is telling the truck not to run. No security light and I turned off VATs in the tune just to be sure.

    LLY new engine won’t start.

    I do believe it’s something with those sensors. When the built motor went in my lmm I had the same issue. The reluctor was bent slightly from being pulled off he crank when it was balanced. Would do the same symptoms only way that it was found was the dealer scoped the crank sensor wires and...

    The block was painted but all grounds were sanded then installed. Actually the ground at the back of the block might not have been sanded. I’ll check. No smoke with the ficm unplugged. And it doesn’t have glow plugs.
