turckster Posted March 7, 2014 Share Posted March 7, 2014 The inj. pump harness connector could be at fault, Check the terminals for signs of corrosion or overheating from poor connection. Have someone crank the engine while you wiggle the connector to see if the engine tries to start. if that's the case, clean the terminals w/electrical contact cleaner. Secure the connector to the holder using zip ties, keep the harness movement to a minimum. Good luck Quote Link to comment https://www.bigmacktrucks.com/topic/34921-05-ch613-e7-350v-mac-problemx/#findComment-236078 Share on other sites More sharing options...
