Happy Thanksgiving, here's what's happening. I used the remote starter this morning, it was about 14 degrees out, it ran for 30 seconds maybe then just quit. I tried once turning the key to see if it would light and it didn't. Picked up new AC fuel filter and put it in. It will not prime. Loosened bleed screw, pumped hundreds of times, nothing coming up. Open drain on the bottom of filter to see if I was getting anywhere and it's dry. I tried cranking it, then opened bleeder screw, slight hissing for a second or two, sounded like air going in. Almost a full tank of fuel. Fuel filter that was in it was only 11 months old, about 30k on it.

I flashed the ECM with stuff Kennedy Diesel, which I couldn't be happier with results, better mileage, much less DEF consumption, sounds more like a diesel. Also have a Fitch Fuel Catalyst which I think I like also.

I'm becoming a believer in a lift pump setup, thoughts on those appreciated also.
Thanks for the help, truck apart and dead in driveway.
