So the other day my jeep going up the hill on paved road started sounding like one of my cylinders weren't firing then all of a sudden died and could not get it back started. Keep in mind my jeep started ticking a little at idle but not all the time.

Now today the jeep started after a jump and drive it around and sounded and drove like nothing happened .... im confused

I checked my injectors and every single one is firing correctly MAF is good..

Any thoughts ? Thanks

 

Start out by checking the charging system.

 

The alternator checks out good

 

When you say it wouldn't start, did it crank or not? If it didn't crank, probably a bad connection (battery terminal, ground, etc). If it did crank, could be many things: CPS, fuel pump...

 

bad carburetor?

 

Yes it did crank turn over try to start.. would a CPS make it sound like a cylinder isnt firing ?

 

Seriously?

 

Haha

 

When my CPS started going south the symptoms mimicked running out of gas. Some sputtering, hesitation, then it shut off and wouldn't start. Sometimes, if I let it sit for a while it would start again but it wouldn't last long.

I recommend you take a look at Cruiser54's Renix tips. Start with step #7 but I highly recommend you make a point to systematically do everything on that list. Especially the C101 connector and grounds.

I'm guessing that you don't know much about the XJ...

 

^Thanks, fellas.. I appreciate the education.

 

so you're saying they didn't come with a carb?


also, to the op, how much gas was in it?

 

Only the 84 to 86 XJ came with a carb. 87 and on were fuel injected. The original poster stated he checked the INJECTORS.

 

valid. apologies.
