Wow tanks wildbill for the research . Still tryn to figure this thing out. the thing that blows me away is when the engine is cold it turns over 2-3 times and starts. No smoke smooth idle runs good.Just don't ever shut it off once it's warm. bought a direct replacement pump with an inlet filter. waitn for the weather to break here. If that doesn't work i guess its time to start looking @ injectors. Should i start by pulling the valve cover and look for leaks around the high pressure connectors? If i unplug the electrical connectors and turn it over i should be able to see a leak right?

It's nice to have a service/repair manual on hand!!

Did you get it figured out?

Update please

Any updates??
