I am looking for some help with my M916A3 I purchased over the summer. It has a 60 Series Detroit diesel engine that is hard to start and idles rough. If I can get it to start it runs very rough at below 500 RPM. After sometime the RPM will climb by itself to alittle of 500 RPMs. The engine shakes, knocks, and just sounds bad. It does smooth out when over 1000 RPM. I already changed the fuel filters. Do you think a bad fuel pump could cause this? It only has 5k miles so it's hard to believe it has bad injectors. Any thought or suggestions greatly appreciated. Thanks
