Attention: TDR Forum Junkies 
Have a 98. 5 (stock) 24V with 125K on the ticker. In Jan 04 the lift pump went out. A trip to Cummins in Cincinnati replaced the lift pump with a warning from the service writer that lift pump failure usually takes out the VP44 injector pump, but only time will tell. March 04 fuel began to leak from the top of the fuel tank. Only seemed to leak when the truck was running, did not leak when truck was off, even if the fuel tank was filled to the neck. A trip to the Mopar men and they replaced the sending / filler / fuel line unit on top of the tank. (Ouch has any one priced this part lately??) The leak has stopped, but so has the ability to start rapidly. I have always been able to start the 24v with the tap of the starter. Now I have to crank about 5 seconds. This problem is more noticeable on truck sitting overnight but also happens on a warm engine. The nights have not been that cold here, but on a couple of nights it did reach temps low enough to bring on the grid heaters. They seem to work (good current draw) & cycle OK. This morning the temp was 62 degrees and the first crank cycle was 15 seconds. I let the starter rest one minute and then hit it again for another 15 seconds. (Sounds like the lift pump is working -PSI unkn) The third time was a charm; it started with the smell of raw fuel in the cloud of white smoke through the exhaust. The fuel filter was replaced and does not seem to make a difference. The truck seems to have normal power under load and has no other deviations from normal except the hard to start. Where do I start to search for an answer?? Thanks for help in advance!
