REDneck Manche Posted February 20 Share Posted February 20 Hey guys. Thank you for any ideas... I have an 88 mj Comanche Sport truck. It has the 2.5L. It is turning over but not starting. I have replace the fuel pump pick up screen, fuel filter, fuel injector, map sensor. I was having an issue after about an hour of driving it would start to bog down and sluggish. Then would shut off and not start, but next morning would start and run fine. Now it won't start, and there is a massive fuel dump prior to turning over and another massive fuel dump when I stop turning it over. Please any help. 20230219_161136.mp4 Quote Link to comment Share on other sites More sharing options...
REDneck Manche Posted February 20 Author Share Posted February 20 The timing is good, #1 tdc marks all line up. And has what appears to be good spark. Quote Link to comment Share on other sites More sharing options...
Ωhm Posted February 20 Share Posted February 20 Check and make sure the fuel is not leaking from this hole. Also, you may have a possible plugged fuel return line. @54bobby Quote Link to comment Share on other sites More sharing options...
