Alright I’m hoping to seek some help on my 1999 24v cummins so I bought this truck thinking it was the best now it’s not turning out to be so I just put a new head on it head gasket arp studs the whole 9 but when I tried to start it it would run super rough and threw a p0237 code and a fault in comapin module code so I un hooked the battery’s to reset the whole truck and now it’s not connecting to my edge tunner and it won’t start or kick the lift pump on and I had some people say it could be the ecm but all the fuses have power and everything turns on in the cab nothing unusel but it’s just not hooking up to the edge and I plugged a scanner into it and it’s showing no codes in the system so can one of you guys please help me I’m at the end of my rope with it 

id pull the edge completely and put the truck back to stock electrically.  

 

 

p0237 is a common code if the edge is plugged into the map, but the box is disconnected from the harness or if the boost fooling function is busted  in the edge.

I agree with disconnecting the edge.

 

Is your WTS light coming on on the dash at key on?
