    LGH (detuned LML in a van) Engine Shuts off at full throttle

    Check voltage output of accelerator. It might be out of range causing ecm to do something weird. What year we talking about.

    No Crank no start

    And if the ecm was replaced, did you get the vats reset, or deleted in new ecm. You also need to verify fuse and power to ecm and bcm are good, along with 12 volts to obdii port. Not sure what year things changed but the bcm has to send the start signal to ecm.

    : Recall # N242454440 MOMENTARY REAR WHEEL LOCK-UP

    According to video, the wheels didn't lock up. Just that at high speed, it shifts into 2nd gear. It would appear that they locked up, but 65+ mph with torque converter locked, I imagine a lot of screeching would take place.

    LML Hydroboost pedal Issue

    The size of the rod is different between the lml and lbz. Which rod did you use. Not saying that's your problem, but I remember them talking about having to enlarge the master rod piston end on some variations.

    Infotainment screen

    The digitizer screen could be going out. Just turn the tuning knob to highlight the dismissal button, then press the center of it. Mines been out for a year or so on my 18. The tuning knob acts like the tab key on a computer to change fields, the center of tuning knob is like the enter key.

    Dorman body mounts dont fit...

    It's the best stuff I've used both on the airplane, and the farm. Just don't put it anywhere you want to paint later.

    911 HELP

    Maybe that far back they didn't have them. Newer ones with in tank pumps do. He might try taking a fuel line and tank cap off and blowing air less than 10 pounds into the line to blow any debris out of the cup.

    911 HELP

    If primer bulb is pulled down, too much vacuum in system, either plugged vent, plugged tank line or plugged sock. If the sock has been changed, a gas sock will not work.

    Service Trailer Brake System - 19 Denali

    I bought a #9107a electric brake force meter. That test the truck side. If truck is ok then it's in the trailer. Is it EOH brakes or magnet style brakes on trailer?

    Fuel injector codes

    Check the wiring, did you have to move any when changing t stats or did you lean on any or drop any tools there? Are these the ones closest to front of engine, and did you mess with any grounds?

    Lbz pulling out of gear

    That's correct. The $29 obd scanner will not read the transmission codes. The p0700 is just the TCM (transmission control module) telling the ECM to set that code and turn on the light. When it went into limp mode do you know what gears you had available?

    I think you need a 4 ft scaffold, and a 6 ft safety sling to fix that tranny.

    Roll Pan hitch

    Would a gen-y hitch work for you? I use one, and it allows me to open the tailgate with trailers attached.

    I need help please

    If it has a separate wire it probably has a separate fuse, but I'm sure you checked that.

    Truck dies at random, no codes

    Just as a precaution, you might try to find the circuit grounds and see if any repeatable events point to a specific ground. With out good circuit grounds it's possible fo voltage to have no easy way to ground so it jumps ship to another circuit and grounds through them. This could be taking...
