Experienced a hard to start condition especially when vehicle was warmed up. After investigating on line discovered that bad fuel injectors for the 03 diesel is a common problem. Replacing the injectors fixed the problem. Pay 5 or 6 thousand dollars extra for the diesel engine because of their supposed reliability and this is what you get. $2700 dollars to fix a flawed design issue. Shame on Dodge and Cummins for sticking it to their customers and not standing behind their product! I was shafted by them with the flawed fuel lift pump and and the cracked dashboard as well. You can bet I will make sure and tell my friends about my experience with this fine Dodge/Cummins quality! I promise that I will make sure that it costs them much more in lost sales than the dollar amount they shafted me with!!!

my truck has the updated fuel pump it is in the tank. the relay is on the firewall and the code reads its low voltage to pump. it will cut in and out and eventually die. the truck would not start. this all happened on the side of the highway took an hour to finally get started. had to unplug all relay and fuse wires. when the truck did start it would only about 25 mph and slowly climb then it would start falling on its face. took me a hour and half to go about 35 miles. changed fuel filter and tried to use starting fluid to start it would not i also tried to pull start and it still wouldn't. i had to trailer the truck the rest of the way home about a week and a half later i started to work on it and i unplugged and plugged everything back in and tried to start it, it popped right off. when i hooked it to a computer it read low voltage to fuel pump. the truck died several times for a couple days i always did the same thing and it would start right back up. later i noticed that the bottom of the relay was bulged down i pushed on it and it snapped up on the relay. it is a rubber bottom in a plastic housing so it would be connected but the wires would push down away from prongs and cause low voltage transfer. months later happened again and it was really cold the rubber was froze and pushed the relay apart not exactly sure this is the cure yet but right now i have it zip tied together to hold it tight it seems to work but its only been a day since ive done this. this problem is the biggest pain in the ass especially when you are in a hurry or need to be some where. its very unpredictable and im not sure how common this problem is mine may just be defected.

After doling out so much money and losing 4 weeks of work over time, it seems that dodge would do SOMETHING about it!! This truck has had the transmission replaced 3 times too. It is not worth buying this vehicle. It does not live up to its name and the company doesn't stand behind it's product. You would think that something would solve the problem but it's not better its worse! This morning it stalled and died in the middle of going down the road full throttle! I had a trailer behind it full of merchandise. Sorriest vehicle I've seen.It's only 4 yrs old. The problem still exists even after all of the recommended replacements. ie: High pressure pump,lift pump,and injector replacement.
