i have a 98 cherokee classic, and i went out one day and it wouldnt start it cranks but will not start. i have replaced the distributor button, distributor cap, cam sensor, crank sensor, coil, fuel pump gave it a new battery and i cant figure out what is wrong with it and I would LOVE some help. a buddy of mine told me it might be caused by a bad map sensor? PLEASE HELP!!!!

 

Have you put a code reader on it to see if it has thrown any codes? Also, have you put a fuel pressure gauge on the fuel rail to see if the engine is getting fuel? You need to stop throwing parts at it and start diagnosing, unless you have a bunch of $$ to waste.

Possible causes of a no start condition (eliminating causes by the parts you replaced):

* Bad fuel pump
* Blown main engine fuse (in distribution box)
* Relay stuck open for fuel pump (also in distribution box)
* Bad coil wire to distributor

These are good places to start. Always go by the KISS Principle. Start simple, go complicated if they don't work.

 

Try starting it in nuetral.If it does then the nuetral saftey switch needs cleaning.

 

couldnt figure it out. so i put it in the shop, they called not even an hour later telling me they were done. shorted wire, $20 fix. now im trying to figure out why my jeep is in limp home mode. do the 98 cherokee classic have the inline fuse on the TCU?
