Engine died after hard stop?!

Hey all,

I was driving this morning when I had to make a pretty hard-stop followed by a turn. I lost all power and now my engine won't start. It cranks, but won't start. I don't believe there is an inertia switch on the TJ...? What could this be? Totally bizarre... Any help is greatly appreciated!

What have you checked so far??
Is there a possiblity the battery shifted and maybe the cables came loose?

Check the spark plugs. A few months ago, I was driving my 96 XJ, and I was in a similar situation as you (coming to a hard stop before a turn) and the engine shut down. I tested everything, and in the end it turned out the the spark plugs were very old.

Thanks for the replies, guys. I don't think it's electrical since the engine is cranking - unless it's an issue with the coil, distributor or wires. These are all pretty new, though... Air intake has never had issues, so I can't see why it would be that. The fuel pump hums when the ignition is turned. The engine will fire up, run about 15 miles, or so, and then just stop? If you give it about a half-hour, the engine starts back up again...

It sounds like something electrical is heating up and then breaking down, sensors can do that.

97 2.5 did the same thing, usually in hot weather
would throw the code for camshaft sensor
replaced it but it would still cut out and die
sometimes it would restart after a short time
some recomended replacing the fuel pump
(the jeep had 120,000 miles) and that helped but....
IN THE END i replaced the CRANK ANGLE SENSOR
local mechanics said this part was go or no go when it failed
but i've found out that it can be intermittent and drive you NUTS
no troubles since... i think the part was $80.00 at advance auto
good luck....post on your results

Okay, so here's the latest... It's happening more frequently now. Someone had suggested that something is heating up the fuel and causing the engine to die? Could that be a faulty pump / clogged filter. The Jeep will run for about 20 minutes, die and then start back up after about 20-30 minutes.

Well, I'm battling some tranny issues right now but I replaced the crankshaft position sensor while I was in there... We'll see...
