Just curious if there is any experience with replacing the ECM on a 24V 2001 Cummins ? Truck in question has approx. 270k miles on the clock . . . up til a couple weeks ago, was running fine. Went to use, and ZERO fuel pressure . . . no start. Lift pump has been changed out to FASS unit. Local mechanic is saying to replace both lift pump & VP44 . . but will ONLY do so, if replaces the ECM - which is NLA, but a couple companies do provide rebuild service . . . question is, does the ECM need to be replaced ? Should try changing the pumps ?? . . . Truck is 2001, 1 ton dually, quad cab.

Appreciate input . . .

Cheers,

Mark
