Hey guys, first post here. (Great forum btw)

(I did a search)
98 Cherokee Limited 4.0 255,000km

I Bought it 4 days ago and i have just done the basic tune-up stuff like
fluids and plugs.

Problem- The jeep runs ok (bit of a rough idle) good power etc, but for some random reason it takes like 5-10 seconds to start or will take the second attempt to actually start and then it fires right up. Now its totally random.

Explanation- I am trying to diagnose a drive train noise so i have the jeep in the air and wheels spinning (don't judge my safety) and I am listening around, shut the truck off, check parts, start and spin wheels again etc..This goes on for a while, all of a sudden no start, so i try a second attempt and nothing, hold peddle down like its flooded and it starts but really badly and wont idle. So i restart with throttle open again and feather a bit so it will idle and its rough but idles. Then smooths out and runs fine...starts like a champ like another 5-9 times while I am doing my diagnostic thing.
So after searching only guess i can come up with cps..it doesn't seem to be fuel related but i also haven't tested it either. Any help from you jeep guys would be great. Thanks for reading my novel.

Thanks


I am mechanically inclined, just to clarify.

 

Thats a good one man! its not loading up from starting and stopping is it trying to wash down the cylinders? are you raising the rpms while looking for your squeek or just idling it? I am also mechanically inclined. i would check fuel pressure next thing. am lost never ran into that. let me know what you find so i know what it is if i run into it at work!
