My 2000 XJ dies like it is running out of gas when it gets warmed up let it set for a few hours and it will start for a few min and do it all over. Let it sit over night it will run longer on first start up. After it dies it still has press on fuel rail, I bleed it off at the schrader(spell) valve and cranked it over and pressure built back up. I'm not getting a engine light when it does this. Can some one PLEASE help me on this, I'm lost on where to look next.

Can you find out if you have any stored code's?

Crank Postion Sensor = CPS. PSI IN THE RAIL IS NORMAL.

Is the cps something that is easly replaced or what do I do to check it?

02tj

Its on the back of the bell housing on the drivers side. two 8 or 10 mm bolts and a plug. not hard to do just hard to get to.

Ok I found it and the hanes manual says it should not have continuity between trmenals B and C ,if so it is good Mine has none between any terminals. Do you think it is only giving trouble when it is warm? And I should go ahead and replace,autozone has one for $75 .
Quick back story, WED. it stumbeled(quick lose of power,like a dead spot) on way to work,and again on way home,one time each. Thurs. night was driving about 35 mph steady it died and started right back.Fri night it died at drive thru window started and ran a few min. died and wouldn't start again untill cooling off.

Buy it directly from Jeep. No lack of threads of people with problems with aftermarket crank sensors. It is WELL worth the extra $25 or so.

I buy plenty of aftermarket parts. I buy my crank sensors only from Jeep.
