On the way into work this morning the engine shut down 3 times on my 95 XJ (5-speed). Lights and radio stayed on, and the engine started right back up with a turn of the key once the jeep rolled to a stop. Seems to happen at low speeds, when taking a turn or come to a stop at red light.

It's had some issues with slight shuddering at start up in the past but never this. I changed the spark plugs 12 months ago and have only but a 2,500 miles since.

Any suggestions on likely issues? I'm thinking either fuel pump or alternator maybe? Not really sure.

I think it's either a loose or failing ignition switch. Pretty common problem it seems, especially since you said it happens during a turn. Someone will chime in soon about it, so just hang in a little bit

Shuddering eh? Sounds to me like your engine has trouble idling. Go check out some threads about testing the TPS, and cleaning the throttle body and IAC.

Had the TPS replaced last year, Jeep was shuddering real bad at low and high speeds. The replacement addressed the issue for the most part but still get some light vibrations upon initial start and sometimes when idling. It's not as much a concern for me as the complete engine shutdowns I experienced this AM.

I would get a new tps....even if you did just get one last year.

Just because you replaced something a year ago doesn't mean you don't need to test it as a culprit.

Well that doesn't seem fair...Ha. I don't have an ohmmeter, is there a way to check the TPS without buying one?

A voltmeter or multimeter will work

I agree with the others. Don't by or replace anything until you do some testing. You can pick up a cheap VOM for under $10 that will get the job done.

Can you point me towards/or provide a good step by step on testing the TPS?

rjlaraway

Going to try and tackle this problem tomorrow morning. My plan is to go to local auto store, pick up some cleaner. Remove throttle body and TPS and clean both. If it doesn't work after that I'll buy a voltmeter and test, and replace TPS if necessary.

Need help. I was about to drive to Autozone tonight and grab a can of cleaner for the throttle body and the Jeep won't even start now. Putting the key in the ignition gives me lights and radio but engine won't even turn a little bit…I have the weekend to figure this out, it's my daily driver and I need it Monday morning, any advice?

Also noticed a ticking noise coming from the drivers side, almost like the same noise you get when your turn signal is on.

Floor mat jammed under the clutch pedal? The interlock switch serves a similar function to the NSS but doesn't fail very often.

Could try giving the starter a tap

rjlaraway

Sorry, give the starter a tap? Walk me through that please

salad

Well you reach in from the top or the bottom, and literally tap the starter or its solenoid with a hammer. Sometimes oil and worn components will create bad connections and things stop working.

Or if you got that multimeter you could troubleshoot the starting circuit.

Did you check fuses?
