I have benn having an ongoing issue with my 99, I just dies for no reason, I dont lose power the engine just dies, I checked all my fluids, its not over heating, it thows a code but goes away after 5 seconds dB I have no idea where to start, my battery and charhing system are running great, any ideas?

 

I don't know much about the 99s but I'd check the important electrical connections, (cps, coil, distributor, ecu, pcm, etc) to make sure there clean and properly connected. Kinda sounds like a bad coil but could be so many things.

Do you have fuel available at the rail, after it dies? Or is the fuel rail dry?

Hows the spark during the time its running?

You might also try Google ing your symptoms, if you haven't already. ..

My 98 backfires once in a while thru the intake when I start it cold but I'll be damned if I can figure out why my computer controlled timing varies.

Good luck.

 

Start your jeep and go under the hood, find your cps wires and start wiggling it around. Specifically wiggle it around back near where it goes into the bellhousing in the back of the engine, alot of times those wires get frayed and start grounding out on bumps/turns and causing the jeep to die.

Also you should be able to pull the code at autozone or any other parts store to see what the culprit could be.

Also could be your ignition switch if it dies when you turn real sharp.

 

rhanks guys ill check that Out

 

Firgured it out the check engine light decided to stay on long enough for me to check the code, it was the crankshaft position sensor
