I have a 98 24V cummins that is suffering with intermittant loss of
boost. It will run fine and then you need a little throttle and the
turbo won't spool up. Sever lack of power, and then BINGO, yer back
in business. Any idea what's the problem? Please post reply...thanx,
john

First thought is a weak lift pump, and a possibly failing injection pump.
Get a fuel pressure gauge on there ASAP and make sure you have adequate
pressure going to the VP44.

i agree with tom. my lift and injection pumps were recently replaced on my
'01.5 cummins 4x4 ($18,499 see http://utilityoffroad.com/dodge) to correct a
problem identical to what you described.

The problem is fuel. check the pumps.
