No Start

[06-cummins]

I Just Replaced The Ecm With A Used Ecm...it Was Reprogramed With My Data. The Truck Did Run With Old Ecm. Installed New Ecm And I Have Weird Codes That Say Undocumented. It Does Not Send A Signal To The Vp44 Relay. If I Jump Power To The Out Put Terminal The Truck Starts And Runs Good. Ne Help Would Be Great Thanks

Is the ECM you replaced a high line ECM? Did it come out of a truck with the factory alarm system? If the truck you are putting it in is not equipped the same the ECM is looking for a signal from the anti theft features on the other truck, and will not crank.

its an 01 i sold the 06....the comp came from and 01 as well n it does crank just no start i think i located a problem in the fuse box but i need to varify today

Let me clarify, the motor will turn over all day long, but will not crank and run. If this is the case your only option is another PCM that I know of.

PCM controls the fuel pump relay. Bad PCM, no fuel pump operation.
