This is an update on my 2500 diesel problem for those interested. Since I
have the extended warranty, the Dealer ordered the recommend replacement for
the uplift pump, one which got installed in the fuel tank. The next day,
I drove the truck to work. The loss of power problem continues. I had to
down shift from 6 to 5th gear on some of the hills when the engine began to
lug. This is while moving at 50+ mph. The truck is going back to the
dealer for more trouble shooting. The truck which I bought new has about
66,000 miles and all service have been performed by the dealer. The fuel
filter was replaced during a previous service. Yes, I'm getting desperate.
I have a 2001 with it seems the same setup.
I had gauges installed and the fuel pressure would go as low as 1 psi
(should be 5) without load or towing anything. I replaced the lift pump
myself (probably nearly the last one they sold as they now do the in
tank pump, which I understand Cummims recommeded to start with).
I have heard that the lift pump failure can take out the main injection
pump, as well as the rear two cylinders from being starved of fuel.
I love this truck! This is our first ever pickup and, even at 11,000
feet, it does have power!

Guys, Thanks for all the suggestions. It was the suggestions that sent me
back to the dealer in the first place, armed with some basic understanding
on what to demand and ask at the service counter. I love this truck too,
and anyone who has driven one is aware of the incredible torque these trucks
have. Without a load, they really will attack a hill unlike any car I
driven. I plan to post the final outcome. Again, thanks
