I recently purchased a 2003 Dodge Ram 3500 with the Cummins Turbo Diesel. No matter what I do, I can't get the thing to start without hitting it with starter fluid first. We've hooked it up to the computer...no codes. Once it's started, it runs fine and will restart with little to no problem. I'm thinking it's something with the fuel pressure? Anyone got any ideas?

There is a pressure check valve on the rail that can go bad. Not letting the rail get enough pressure. Also you need to check your lift pump. See what if any pressure is pumping. Can you get a hold of a fuel pressure gauge. That is where I would start. Check for pressure at the lift pump.

win the key is turned to the on posision the lift pump scould run fot a second or two. then after the truck starts the pump will run continusly. if the lift pump dos not come on the truck wont start. That is what i would try first. if pump dose not run to prime, trick it. It sounds to me that your lift pump is most likly the problem. All so .... if you continue to use starter fluid you will have a hole new leavle of greef to deal with.

dont use starting fluid on these engines. . .once the stuff hits the grid heater if it kick on can cause some VERY BAD things to happen.

sounds like the check valve on the rail, but could also be excessive return on an injector. a shot of ether just allows the pump to spin faster to build up enough pressure. hope this helps.
