On my 1996 Jeep Cherokee Country the fuel pump wont engage and there is no spark coming from the coil to the distributer I changed the ignition switch looked over the fuses and battery wires checked other wires only engine only rolls over

spark box or coil pack going out. one day it just wont start anymore

maybe cranksensor

I would make sure you have voltage to the coil. Could be a fuse or relay problem. Is the check engine light on when you turn the key on ?

Look for a crack in the distributor cap or the coil where the cable comes out. you are losing the spark somewhere between these two.

Sounds like you need to have your ecu engine computer repaired. It's a common problem with that generation Jeeps. Try leaving the ignition key turned to the on position, for appx. 30 minutes, to see if the check engine light does finally come on, and if the Jeep will start then.

Check spark at plugs. If no spark consider coil.

Great...glad to hear it's up and running!

check ignition pick-up coil and ignition module

You need to replace the crankshaft sensor, it's mounted behind the engine at the top of the bell housing on the drivers side. It is a pain to do, but a very common problem.

sounds like your crankshaft position sensor has failed it is located on the bellhousing and has a thick black lead off it with a three wire plug, also it should have 1 ten mm bolt holding it in place, this provides an impulse signal for spark and fuel injector pulse and the car wont run without it -jeff ps please rate and goodluck http://www.autopart.com/CrankSensor/CrankSensor1992JEEPCHEROKEE.htm this is also a suspect part but my money is on the crank sensor, this part is this camshaft sensor located in the distributer and will not kill the fuel in most cases just spark http://www.rockauto.com/catalog/raframecatalog.php?catalog=301&partnum=C1929&a=FR301-C1929
