  3. 911 Problems Forum
    Hi everyone, I recently acquired an '02 Chevy 2500HD w/ Air Dog II Lift pump, and I'm having a hard time reliably getting it started. Once it gets going, it runs fine, no smoke, no rough idling. Here's what I'm seeing: Fuel & Air filter recently changed in stock housing, AirDog filters still...
  4. 911 Problems Forum
    Truck had light hard starting after fuel filter change (might not have anything to do with problem), thought not primed well. Pumped up the fuel pressure. Truck sat for 4 days. Try to start, turns over 1 revolution then stops, then again, and again. No light indications for roughly 5 cycles...
  5. 911 Problems Forum
    I have a 2002 Chevy 2500hd lb7 with 220k miles on it. Injectors we’re done at 180k miles, new cp3 pump was installed at the same time, fuel lines have been replaced, fuel filter housing has been replaced, a Fass pump has been installed, new FPR. Pretty much everything you can think about for the...
  6. 06-07 LBZ & LLY Duramax Powertrain
    Ok I'm new here so go easy on me. I have an '06 lbz duramax that has 250k on it. I purchased it 20 miles ago. As I was cruising at 60mph I lost oil pressure and it died and left me on the side of the road. So I towed it home replaced stock oil pump with a pinned wagler with the engine in the...
  7. 911 Problems Forum
    I have a 2003 lb7 ran great when I first got it 161000 miles except sometimes the starter grinds no teeth are missing on the flywheel and I put a new starter on still does it. Then it at times would start right up and sometimes it wouldn't if I let it set for an hour or sometimes all night it...
  8. 01-04.5 LB7 Duramax Powertrain
    I've got an 04' silverado with a vin 1 lb7 and once every couple months it will crank but not fire no matter how long you crank. I replaced the primer pump, fuel lines and fuel filter. It changed nothing. I can prime it up tight with no air and as soon as I crank it I lose the prime. I can prime...
  9. 01-04.5 LB7 Duramax Powertrain
    Hello everyone. I know this has been discussed many times, but I can't find my specific issue. Truck is a 03 LB7 with 260k on it. I do the fuel filter religiously every oil change because of these pesky injectors. I have also had to replace the passenger side bank of injectors in the last 10k...
  10. 07.5-10 LMM Duramax Powertrain
    I have a 08 lmm will crank but not start. Started up first thing in the morning noticed it was a little “noisey” like a rattle. Checked oil ect everything was up to par. Drove appx 10 miles and started noticing a vibration when on the accelerator. Pulled into a gas station and it had a huge lope...
  11. 04.5-05 LLY Duramax Powertrain
    I’ll start this off by saying I haven’t heard this truck run yet. LLY. Doesn’t prime. I believe there’s air drawing into the fuel system. Previous owner replaced fuel tank, sending unit, fuel lines up until where they turn up at the fire wall under the cab, filter housing and has a cat filter...
