I've got 2001 cummins sport 4x4! 180,000 miles on this bad girl beautiful truck fully loaded leather and wood grain.
Anyways I'm at my last thread with this non driving turd!
I just replaced the vp 3 weeks ago including lift pump. Long story short she is stupid. She died on me last week like she ran out of fuel well she never did took forever to get her started. Well she's been running pretty good for a couple of days well now this morning she was surged once every 5-7 mins. Then totally died. I did have to crack one injector but she fired right up let her idle then took off truck died as soon as I got to 30 mph. But now she starts right up after no cracking injectors well she won't rev up over 2500 Rpms I pulled several codes
P0230-lift pump circuit out of range
P0215-control circuit failure to injection pump
P1693-ecm ****!
P0237-ECM ****
P0122-apps voltage low.
Well I'm mind fked!!!
ECM bad???
Well after work I fired her right up gave her a lot of pedal and she would redline it wouldn't this morning? Wtf!? Stupid truck. Also the other day she did act like she got really hot not in the red but well over normal killed it for a min then started back up and it went immediately back to normal running temp!
its crazy any help

 

Need a little more info do you have any mods programmer etc?
I would say you have a battery issue low voltage, poor connections at the cables.
Double check your harness at the ECM and VP.
Also if you removed a HO pump you should reinstall a HO pump. If it was a SO you should install an SO sometime this has caused driveability problems.

 

Any updates?
