Guys;

Thanks for the comments. I am printing them all and taking them to the mechanic. I did remove the crossover pipe, made sure it was clear and that the flapper valve is working freely. I did not remove the plastic cover but I know my mechanic has been all over the injection system. He is telling me there is no "Lift pump" in this engine, that the fuel is moved from the tank to the engine by the "fuel distribution system". I think what he is saying is that the only fuel pump is the "vacuum" created by the injector pump. Does that sound right? Now they are speculating that I have a problem with the injector pump, they have to take it off and send it somewhere for overhaul.

I keep reading on the forum about similar problems caused by the EGR. I did take that off and clean it early in the process and I ran the engine with the EGR disconnected from the exhaust manifold and with the vacuum hose disconnected from the EGR. None of that made any difference. Is there anything I am missing that could cause this to still be an EGR problem?
