HELP!! got a new one by me here, hopefully one of you guys out there can shed some insight for me. I have an 02 cummins and it just crapped out on me this morning, didn't die but went to no power and very rough running upon acceleration at first and then when idling as well. Haven't let it run very long while this is happening due to paranoia (have already replaced the injection pump). Had a mechanical guage on it for most of the weekend and low fuel pressure was a solid 12 at idle and didnt drop below 8 on load. It does not sound like it's running out of fuel when it starts acting up. No check engine light whatsover and no new codes. Watched the scan tool data and the only thing I could see that might be out of whack was my CMP rpm reading which was always zero whether at KOEO, engine idling or goosing it a little. Can't find any solid info as to what I'm supposed to be getting here. Anyway, any potential insight here would be greatly appreciated.
