First check for spark at any of the sparkplugs.

Your timing is locked. (distributor is installed with no adjustment feature... on 02's you may not even have a distributor as it's replaced by the cam sensor) All timing and fuel mixture is controlled by the engine computer. Main inputs to the computer that influence changes are the throttle position sensor and MAP sensor but all sensor inputs are evaluated.

Check your throtle postition sensor. It monitors what postion the throtle is at and sends that info to the ecm. It will go bad and cause that problem.

1-check fuses if fuses ok go number 2.
2-check for power to the crank shaft sensor (test light) for a positive if no positive replace asd relay.
if you got power to sensor check for signal while cranking on the engine (connect the test light to (+) on battery if no signal replace the sensor. hope this helps.

TRANSMISSION SENSOR FOR A GRAND CHEORKEE 2002

Crank sensor is generally located on the bellhousing 11 o'clock position looking from the rear. It is always even with the flywheel as it gets it's trigger from that.
It is not easy to reach it but it is not impossible to do. If yours has spacers, remember that it is better to use too many than not enough (too close to the flywheel and it will self-destruct) it can pick up a signal nearly 1/4" away from wheel though. Since it's not easy to change, make sure you test it before you decide to replace it though!
