    02 LB7 Crank no start

    A few seconds of cranking should dray out most of the fuel in any cylinder. If it continues to pump out fuel mist, you either have leaking injectors or the FICM is still active. Maybe just pull the harness connectors right off the FICM if you're not sure on the fuse

    2016 Won't start

    You might be confusing the two terms. "Crank", "cranking", and "turns over" are typically understood to be synonymous.

    I think all of them are worse then the three mile island. The media way over hyped the issue.

    I remember hearing all about Rocketdyne a bunch. I was born in LA and spend most of my early life down there. Would see the rocket trails from the ones launched out of vandenberg. The colors right after sunset where also neat to see Those Saturn V F-1 engines where on another level. Would have...

    09 LMM white smoke

    If the fuel pressure is good and steady. Then it likely points to injectors. You could because it free, clean all the injector connectors and maybe even apply some silicone or dielectric grease to them and see if it improves. Wouldn't hurt to see if you can source that GM injector cleaner. I...

    That's awesome. We have an Aerojet up here in Folsom. But they seem to be sleeping most of the time. Not much comes out of there anymore. Many people here used to work there. Now many don't even know what they are or that they even exist I believe they assisted in the testing and modifications...

    02 LB7 Crank no start

    I forget your's is an 02 Duramax. The wiring was weird for the pre 03 years. The 03+ calls the FICM fuse EDU. Your's I think is fuse #1 for injB

    I watched it. Set an alarm to remind me. Was pretty cool. This time the furthest any human will be beyond Earth Another interesting data point. This Artemis project is 100 billion. The California high speed rail is now 135 billion. How is it cheaper to send people the the moon then to run a...

    09 LMM white smoke

    Main rate bouncing between 5 and 11 mm3 could possibly indicate a bad fuel pressure regulator. 9 + or - 1 or 2 mm3 is typical and what one should see with a healthy fuel system. 5 mm3 would indicate that most or all the injectors are putting out too much fuel. I say most or all because the...

    Fuel rail pressure

    Maybe slipping transmission? Make sure to log that too if you can't see anything obvious in the tune

    Is it, x2 This might be cheating because it's a custom one off and not on the market 😁

    Duramax in an old 6x6 in Germany

    If no FICM, then it's an LBZ (depending on year, it might have been called an LLY, but identical to the LBZ other than programming. Which can be fixed) Just find an LBZ wiring harness from a truck and pull out what you need and rewrap it. You'll need efi live or HP tuners to turn off all the...

    Parking brake mechanism issue? DRW 3500 Won't take up slack.

    Sounds like a stretched cable, even though you said you replaced it , or you didn't adjust the peddle

    Duramax in an old 6x6 in Germany

    Welcome Does your engine have an FICM? If so, you can use basically any LLY truck harness. If not, then any truck LBZ harness. What speed Allison did you get? The LLY has a 5 speed and LBZ uses a 6 and they are different TCMs. Maybe a little more information on what you have
