95 YJ Stalls while driving

Jeep starts right up. Started driving down the road and it just stalls out. Thought bc it wasn't warmed up. Since it's a manual trans it jump starts back up and bucks bc it stalls and jump starts itself when I'm driving. If I put the clutch in or shift to neutral sometimes it just stalls out. It starts right back up and sometimes can go miles before it might cut out again. There is no pattern to when it might happen. Fuel pump seems ok. The one thing I did notice is that the distributor shakes as if the entire unit is loose but when the engine is off I can't move it. It also feels very hot to the touch under the cap on the assembly. Any other possibilities?

I'd check the crankshaft position sensor. Sometimes they stick open or closed and kill the engine.

95's don't have an ODB. How do you check the codes on a 95 YJ?

Key dance, count the flashes.

Search the YJ Tech FAQs.

The distributor is not supposed to move. Any movement of the whole unit could be because the hold down bolt has loosened up or the distributor shaft bushings are shot.

The only moving part you should see is if you remove the distributor cap and someone else attempts to start the engine. The rotor should turn along with the center shaft of the distributor.

Do you know what was good about the good old days? I wasn't good, And I wasn't old!

Senators and Congressman should wear uniforms like NASCAR drivers so we could identify their corporate sponsors....

Agreed! Start looking here.

While the distributor cap is off, use a 3/4" wrench to rotate the crankshaft pulley forward & backwards while watching the rotor for movement. Excessive play in the timing chain may not be your issue, but it sure is easy to check anytime the cap is off!

All good ideas. I'll check them all. I'll let you know what it turns out to be.

OK I think we found the problem. Bought a new crankshaft position sensor $88. Not the problem. After installing it the jeep stalled out 3 times in a row. Double checked distributor and that check out ok. Ran key dance to check error codes and nothing out of the ordinary. Vacuum hose on pump was fixed. Still nothing. Started to wiggle some of the wires just for the hell of it (running out of ideas) and when we got to the coil wire, after wiggling it the engine shut off. Took of the harness clip and attached the wires without it. The wires snap right in. Jeep ran fine. Put everything back together and took it for a 60 mile run. Didn't stall once.

And the lesson is...a big bad jeep can be brought to a grinding halt by one measly stinkin' loose wire! Good show finding your problem!
