The same thing happened to my buddys 02. The stock lift pump on 24v are known for being weak. When they go bad they usually take out the injector pump too. My buddy just complained to Dodge till they fixed it but he only had 50,000 miles on his truck so it was covered under warranty. You should call Garrett at Pure Diesel Power he's one of the sponsers of this site & knows his Dodges. Other wise your looking at about $1400+ from the Dealer. I'd spend the $$$ & get a F.A.S.S. lift pump & then get crazy & upgrade to a P7100 injector pump!

You can skip the P pump unless you really want some power.
