MX13 Parts Engine
Not sure if the forum is the place for this or not but does anyone have any experience with an EPA10 MX13 main engine wiring harness going bad? It’s in a ‘12 T800 and injectors 3,5,&6 are not firing. We’ve replaced the injector wiring harnesses (the top plug on the ecm) and put a used main engine to cab wiring harness (the middle plug on the ecm) on it but now the shop thinks maybe that harness is also bad. We’ve ruled out the injectors because we swapped them with the other three and our problem stayed in the same holes. The used harness I put on looked very good condition, I just can hardly believe that we don’t have another problem somewhere else. Just don’t want to throw a 2000 dollar harness on just to see if it fixes it. The shops at there wits end on it and so am I. Any ideas?
