My 85 6.2 diesel is stalling after i let off the gas, such as rolling to a stop sign. Changed the fuel filter, cleaned the air filter, same thing. Any ideas? fuel injector pump? Please help

Hi Rene This is the same guy in the earlier thread who got air in his fuel line when changing fuel filter.
Cornflake you most likely still have air in the fuel system that you haven't bled out properly. I remember you said that it started ok but was still running rough after bleeding? That'll probably be why it stalls when you let off the gas now. There's still air in system.
Agree with Rene, it could be the lift pump. It could be sucking air through a leak in the filter housing too. Did you make sure the filter was seated properly and all the air bled out of it? And did you bleed the injector pump properly?
You gotta check these before you start replacing lift pump etc.
Running rough and stalling are classic signs of air in the system IMHO.

Thought i bled all the air out, possible still some in there. The thing that gets me is it's doing the exact same thing as before i even took the filter off. I went looking through my chilton's and couldn't find anything about a lift pump, then found out from a mechanic that it may not have a lift pump at all
Step #1, stop listening to that mechanic...he is an idiot.
Step #2, read this thread I linked.
