Default turns over but wont fire up

I just bought a 92 cherokee briarwood from a guy at work. it had been sitting for awhile but was started until battery died. I put my truck battery in and was driving it for 2 months with no problems. I have changed the spark plugs, wire, cp sensor, fuel pump, fuel filter, ignition coil, rotor button, and distributor cap. I pulled out of a driveway and moved like a foot and motor stalled. I have fuel in the rail and motor will crank but wont start. anyone have any ideas? sitting in a parking lot getting towed to friends house today.
