    EPA strikes again

    When will the EPA mandate DEF and SCR on commercial airline jets? I could just imagine the engines going into limp mode at 36k feet and reduced speed to 200mph.....lol

    Injector hung open possibly??

    I got the grounds cleaned up. There is no ground on G109 above. The hole is there but there has never been a bolt in it. I only was able to drive about 10 miles and she ran normal. I'll post back if she acts up again.

    Injector hung open possibly??

    I didn't think the "ice pick" trick applied to the '06 LLY/LBZ???? All the searches I did regarding the "ice pick" let me to the true LLYs. Harness was the first thing that came to my mind. Also couldn't find if a symptom of a bad harness came with large amounts of black smoke.

    Injector hung open possibly??

    I've search for about 2.5 hours on the net on different forums, google and youtube. I'm not expecting someone to point to exactly what my potential problem maybe, but rather some advice or educated guess as where to go next. Figured this is by far the best duramax forum for that. Here goes...

    Well things got fun today. Pulling a trailer the ABS, brake light, airbag light, battery light, security light were on. Gauges went dead. Locks started locking and unlocking by themselves. Radio went dead. Power windows are dead. Tow/haul mode stopped working. Pushing the button on the end...

    Another code thread

    Never did make it to the shop. Drove 7 hours to work Sunday night with just the ABS light on, no "Service Brake System" message or Brake light on. Started truck Monday morning and ABS light went off after 2-3 minutes. Drove another 7 hours home with no lights, no codes. ABS light came back...

    Another code thread

    Alright, checked box in rear of truck, checked connectors at ABS module, found no broken wires that I could see, checked stater wires, tested ABS sensors in the new wheel bearings. Nothing out of the ordinary. The mysterious gauge cluster/head light delayed power up seems to be gone for now...

    Another code thread

    Something I notice to this point above, when I turn the key to the on position, I can hear a sound that sounds like the electrical is building up and boom, power to the cluster, radio, auto head lights (if it's dark enough), etc. The only thing that is on during this 3-6 second delay is the...

    Cleaned up the ground under the driver's door, pulled ABS fuse, checked connectors to the ABS unit and no change....

    Another code thread

    I'm having a similar issue. I have the "service Brake system" message with the Brake and ABS lights and chimes going off. I checked the wheel bearings, they were bad. Put new bearings on, no luck. I checked the batteries, unhooked them, tested them, all good there. Removed the edge insight...

    Fuel filters cut open, what do you think?

    Thank you. I've often thought about doing away with the CAT and running the p553203 on the factory head. If the lift pump fails and bypasses I would be running without a water separator with that CAT filter. I think the Donaldson is a 3um which would be better than the CAT according to your...

    Fuel filters cut open, what do you think?

    I never intended to have 3 filters, but after being stranded at -13 at 1:30am because of a gelled/iced filter, I decided to get the lift pump with fuel heater. I was running the Donaldson P553203 on the CAT adaptor at the time. I haven't have a problem since and I have great filtration.

    Strange clunk on shutdown

    Yes. Didn't see anything obvious.

    Strange clunk on shutdown

    I got a chance to pull the serp belt and start the engine. No clunk. I did this 5-6 times and no clunk. All the pulleys feel tight and smooth when spun by hand. So I reinstalled the serp belt and wouldn't you know it, no clunk. I had the wife start and shut off the truck 6 or so times while...

    Strange clunk on shutdown

    One other thing, I recently changed the oil and there was no change in the clunk.

    Strange clunk on shutdown

    Okay, had someone with a flashlight crawl under it as I shut it off a dozen times and nothing obvious. One thing I did notice, I cold started the truck and moved about 50' in my driveway and shut it down and no clunk. The next thing I'm going to try is to warm up the truck and remove the...
