TJ finally quit.

[untamed]

Well after a few months of trouble shooting and replacing parts, thinking I had it fixed each time. My TJ left me on the side of the road. It was running great then I went over some train tracks and it decided to studder and sound like it was flooded. My gas guage went from 3/4 tank to 1/4 tank. I put it in neutral pressed on the gas and it reved up great then went into drive and had power again. Fought it all the way to work like that. Got off work and it fired right up. The gas gauge was back to normal drove it 3 blocks it did the same thing so I pulled off the road and it stalled and won't start again. I'm at my wits end. Need help if anyone has ideas what the hell happened. Thanx in advance.

Have you checked the wireing coming through the firewall for shorts? My dad had a yj that did what yours is doing. By accident and after 2 days of my brother and I looking at it, I put my hand on the bundle of wires coming out of the firewall into the engine bay to rest a minute and the jeep shut off, tried to restart and nothing, I wiggled the wires and it started right up. We ended up taping about a 6 inch section of the wireing harness and it didnt do it again.

I'm experiencing similar symptoms except for the fuel gauge issue. It seems to run perfectly and then in the afternoon when it;s hot and the A/C is running (under load) it will miss and stumble real bad. I have replaced a fuel injector and the coil pack and it's still giving me fits. I wonder if it's the fuel pump, because my started doing the same thing after going over a rather rough bump in the road, similar to your experience with the railroad tracks... I'm at my wit's end as well because I feel I'm just throwing money and parts at it and not making any headway!

I agree with 6jeepcj that it sounds like a wiring issue....hitting the bumps could be causing the short(or open). check for maybe a loose connection somewhere....

Ok first thanks for the info. I was starting to think it was an electrical problem to. Now an update.... I got to my jeep this morning to tow it to my works shop and just for poops and giggles I went to see if it would start and low and behold it fired right up....but when I put it into drive it acted like it was flooding again so I put it in neutral, reved the engine to about 3500 rpm threw it into drive all the way to first gear (its an automatic) and tore out of the parking lot like a bat out of hell...well if bats can go 25 mph.... I kept the rpms up the next couple of blocks and made it to the shop. When I parked it it diddnt die on me instead it purred like a kitten. I haven't tried to start it since. The next couple days it will get my full attention. So I'm trying to get as many ideas as possible as to what it can be.

No check engine light?

That's the thing...never a check engine light.

Ok...update... I started the jeep up and started looking for short or bad wire and I found it...there was a connector resting on the intake manifold and when I moved it it shorted and the engine quit. I moved the connector and wire off the intake and started it up again. I then moved the connector and it shorted again and it killed the engine. The wire goes to the crank shaft sensor. So I cut out the connector spliced the wires together and now........IT WONT START!!!!! Why??? What was so special about the connector... I removed the nev battery terminal before doing it. Could I have blown a fuse? If so which one? I looked at all of them and they looked fine.

Mine was the same, with it running in the drive way wiggle the connector it wanted to die, swapped the sensor and problem solved my guess is it the wire from the sensor you spliced out the connector but the problem is further down the wire.

dang, that sucks. cut out the connector but its actually the sensor is bad.

I think that's what happened...the wire was bad at the connector on the sensor side. But I left enough wire on the other side to put it back on...the thing that sucks about living in a small town is that no parts at parts stores... ill let ya know if a new one fixes it.

Ha! We chose this little one horse town pre-jeep. We lived in Portland OR area before we moved here. I was spoiled there when I had my 89 yj. But I wouldn't change it for anything.

 

[TrailRatedRN]

Lol. I grew up in an area where you had to drive about 1/2 hr to get to any stores. Now I ***** if it's farther than 5 mins. Haha

 

[untamed]

But....the good thing is I can park right in front of wherever I'm going. Not pay to park or walk five blocks to get there. And traffic.....there is none.
