Jesse J Posted December 2, 2021 Share Posted December 2, 2021 Well my jeep was running great until yesterday after school driving home about 500 feet from my house it sputtered and died. spent the next 4 hours trying to get it to run including sawing off my exhaust muffler back because 2 people at school told me some dingus shoved a rag up my tailpipe. Ended up towing it home with my buddies xj. Started fluid didnt work. Cleaned the plugs this morning because thats what was wrong the last 2 times.

89 MJ Posted December 2, 2021 Share Posted December 2, 2021 Do you have fuel pressure? Can you hear the fuel pump when you turn the key? Can you confirm that you are getting spark? Link to comment Share on other sites More sharing options...

89 MJ Posted December 2, 2021 Share Posted December 2, 2021 I’d check for spark then. How old are your cap, rotor, plug wires, and spark plugs? Link to comment Share on other sites More sharing options...
Jesse J Posted December 2, 2021 Author Share Posted December 2, 2021 old ish. might be worth replacing. my plugs are pretty new Link to comment Share on other sites More sharing options...
Pete M Posted December 2, 2021 Share Posted December 2, 2021 not that it's ever bad a bad thing to do a basic tune up, but before you fire the parts cannon, check for spark coming out of the coil. do you have an inline spark tester? Link to comment Share on other sites More sharing options...

Jesse J Posted December 3, 2021 Author Share Posted December 3, 2021 no spark judging from the videos I that I took from my engine bay with 2 different sets of plugs. no spark when I put a plug in the wire from the coil to the distributor idk if thats an actual test but I thought I would try Link to comment Share on other sites More sharing options...
Pete M Posted December 3, 2021 Share Posted December 3, 2021 I've got no way of knowing if you held them close enough to get the spark to jump. did you test the CPS resistance? Link to comment Share on other sites More sharing options...

Jesse J Posted December 3, 2021 Author Share Posted December 3, 2021 cps checks out I am skeptical of the connector one of the male pins is bent and the female is shoved back in there but I think they are touching Link to comment Share on other sites More sharing options...
Pete M Posted December 3, 2021 Share Posted December 3, 2021 "I think" is not the same as "I know". there are only a few things needed to get spark. one of them has failed. any parts store will have that spark checker. possibly even walmart.

Jesse J Posted December 3, 2021 Author Share Posted December 3, 2021 jumped the connector and it fired up! there is quite a bit of engine smoke I think because I didnt bolt my downtube onto my manifold correctly (because that was my first fix when I heard about the exhaust rag Link to comment Share on other sites More sharing options...
