98 avenger cut off while driving now it will turn over but won't start? on 1998 Dodge Avenger

My son was driving his 98 Avenger at 45 mph when it cut off. Now when you try to start it the engine will turn over but won't start. My mechanic has checked the fuel pump, changed the coil, cam shaft sensor, changed the computer, and checked for loose wires and he is been left scratching his head. Also new timing belt was installed a year ago. Looking for anyone who has any ideas what might be the cause the problem. Thanks

I have a 2008 Dodge Avenger 2.4 cylinder cut off issue, to make a long story short here are some of Chrysler made vehicles engine cut off issues:
Dodge Avenger, Journey, Jeep Patriot, and Compass vehicles. A new adhesive used in the power train control module (PCM) manufacturing process can cause the printed circuit board to break. This can cause the engine to stall and cause a crash without warning. Dealers will replace the PCM free of charge. The recall is expected to begin during November 2008.
Dodge Avenger vehicles equipped with a standard tire pressure monitoring system (TPMS). Unused electrical connectors for the TPMS may become corroded and could short circuit, which can cause a variety of conditions including engine no-start, dead battery, an inoperative cruise control or remote start system, and/or engine stalling. Engine stalling could cause a crash without warning. Dealers will seal the wires for the TPMS free of charge. The recall began on April 15, 2008. Owners may contact Chrysler at 1-800-853-1403. 08V152

Chrysler dealers will remove any corroded connectors and add protective covering.
fix problems with the front driver and passenger side door latches.
and the TIPM module replacement needs.
Did the timing belt break? Was it replaced as per the maintenance schedule? If the timing belt did break you most likely have other internal problems as this is an interference engine.
The timing belt was ok-it was replaced less than 5000 miles ago.
