I was driving down the road turned into a parking lot and it stopped running, checked injectors fuel was coming through, replaced spark plugs, wires, distrib. cap and button. still won't start, turns over fine. tell me help me.  

There is a post of mine on here, i had the same problem with my 91 4.0  cherokee, it was the cam sensor which is inside the distributor. Some other things to check are the crank sensor or again like ine after the cam sensor make sure the exhaust is not blocked, I had one of the plates in my flowmaster bust loose on the tow truck ride i assume and the damn thing would not start after i changed the cps. If you have a repair (chilton or haynes) it will tell you how to read the trouble codes. If you don't have one you can email me at mefreeman30@hotmail.com and will try to help as much as i can
