First off, I have very little knowledge of fuel systems so any and all help
would be appreciated. I have a '01 Ram with the 24 valve Cummins and 82K
miles on the truck. I just recently changed my fuel filter as part of a
regular 'service'. I filled the filter bowl about half way with ATF like
usualy (I hear this helps keep injectors clean) and started the truck. Died
after a second or two like normal and when I tried the restart and listened
for the pump filling the bowl, I heard a crunchy sound along with a gurgling
sound, not the normal hum. Is the pump on its way out? I saw a thread here
about lift pumps going bad often. Could this also be part of my
lack-of-power problem? (sometimes when stepping on the pedal nothing
happens for up to 30 seconds, then it'll spring to life.) But that's a
whole 'nuther story...

VERY common for the lift pumps to go out on these. Fortunately, I belive it's
covered under the Cummins portion of your warrantee. Check out some of the
threads over at:

That was probably your injector pump running dry. When you change the fuel
filter, don't start the engine. Just "bump" the starter and let the key
spring back, leaving the ignition on. You'll hear the lift pump run for
about 20 seconds. Do this three times, then crank up.

ATF contains nothing that will clean injectors better than #2 Diesel at
22,000 pounds of pressure. Don't bother.

move fuel to the ip, if it doesn't the ip will go south on you. They cost
around 1K, a lift pump is around $140.00. A lift pump can last for more than
30K or have been known to fail right out of the box. I'd strongly suggest a
fuel pressure gauge to keep a check on things.
