Hi. I had the same problem on my 2004 Dodge Ram 3500 Cummins. I went to the dealer and they did a bunch of diagnostics and they replaced my fuel pump. At the same time they put in a retrofit kit that moved the fuel pump to the inside of the gas tank. I have not had the problem since. The cost was about $1,200, but my 100,000 mile drivetrain warranty covered it and I had to pay the $100 deductible.

When the key is turned to the start position, the pump should run for about 20 seconds. Do this 3 or 4 times to prime the pump.

If it still doesn't start, the bad lift pump may have damaged the injection pump. Crack a fuel line loose (don't remove it) and turn the engine over, you should have fuel at the fitting.

It was located on the drivers side of engine close to fuel filter housing, but dodge has been selling and installing kits that change it to the in tank style for quite some time, so if not on block it must have been converted at some time.
