01 cummins cranks but wont start
 

I was driving down the road and my Cummins just died on me. everything I read said it was the injection pump, so I changed that but still wont start. I checked all my grounds got new batteries, and good fuel pressure. I bleed all the air out of the lines, and even tried spraying ether but still nothing happened.I have some codes that said cam shaft sensor and crank sensor and my throttle position sensor. could those cause it to not start or is something else? open for any ideas to get her running again.

Are you getting power and ground at the injection pump does your tach work cam sensor sends signal to tach. my 01 only has a cam sensor no crank sensor.

What is the tach? I just put a new cam sensor in today and it still didn't do anything?

Crank sensor is bad if your tachometer isn't registering. 👍

tach is the rpm gauge on the left of the speedo. If you have rebuilt injection pump a working fuel pump that comes on has pressure and fuel supply you probably have a wiring issue on your injection pump. this is a link for a no start read it VP44 Diagnostic here is a link for a wiring diagram Mopar1973Man's Dodge Cummins Articles - Dodge Ram Turbo Cummins 24 Valve Engine Wiring

I was finally able to narrow it down to my airdog lift pump is there anyway to get just the motor or do I have to get a whole new assembly?

If you bought pump new, call them they will replace it.
