Muncher Posted June 18, 2022 Share Posted June 18, 2022 In need of help quick. My truck was just priming and running now it won't. Occasionally it will just start priming and not stopping but only with one relay I switch it out too. I cut the ground at the pump and grounded it closes and it still doing the same thing. Also my fuel pump gauge is way above full. What could be wrong? Also My fuel rail was just leaking before this if that could have anything to do with it.

eaglescout526 Posted June 19, 2022 Share Posted June 19, 2022 Highly recommend gettin that C101 cleaned. Get a butt load of brake cleaner or electrical contact cleaner and be prepared to spray and scrape gunk out. Link to comment Share on other sites More sharing options...
Muncher Posted June 19, 2022 Author Share Posted June 19, 2022 Yeah i will do that. I belive my ign might be bad though. No tach anymore and I belive ecu makes tank prime so it could make sense that it's bad. Also my rem gets no power now and the diagnostic port is powered by the ign Link to comment Share on other sites More sharing options...
eaglescout526 Posted June 19, 2022 Share Posted June 19, 2022 Damn. An ICM sounds possible. You made sure fusible links didn’t blow right? Link to comment Share on other sites More sharing options...
Muncher Posted June 20, 2022 Author Share Posted June 20, 2022 No how do I do that. Link to comment Share on other sites More sharing options...
eaglescout526 Posted June 20, 2022 Share Posted June 20, 2022 Test for continuity from the fusible link to what ever it powers. So like the fusible link to the fuel pump relay would be the idle one to test. Link to comment Share on other sites More sharing options...
Muncher Posted June 20, 2022 Author Share Posted June 20, 2022 Ok. Is the fuel pump relay the 2nd or third one in from the front of the jeep. Cause diagrams say 3rd but I had to pull the 2nd one to get it to stop priming when it would randomly start Link to comment Share on other sites More sharing options...
eaglescout526 Posted June 20, 2022 Share Posted June 20, 2022 It just depends. Those blocks do separate from each other and someone could’ve rearranged them. Link to comment Share on other sites More sharing options...
