New timing belt, new cam sensor, new crank sensor, new plugs & wire, new battery New water pump, new alternator. Starts first time if you don't touch the accelerator & runs good till you kill it & then it just tries to start but won't. It sounds like it's firing & about to start but just won't. I don't know what else to do. Any help appreciated.
You did not say anything about the fuel system. Have you checked the fuel pressure ? Has the fuel filter been replaced this year ?
Is the check engine light on when the engine is running ?
Could be low fuel pressure or a faulty throttle position sensor among other things.
SOURCE: Won't Start.
These trucks have a problem with the catalytic convertor blocking the exhaust causing a no start condition, the three things you need to start fuel, spark and air. Try disconnecting exhaust in front of cat.
SOURCE: Engine will not start!!!
was the timing belt changed, since it overheated the cam may have gotten tight and the belt might have jumped 2-3 teeth and you still would have a spark and fuel pressure.
SOURCE: 1998 dodge neon. Engine tries to start , but won't catch.
well it sounds to me as if the timing bet as jumped its time,mabe not much a tooth or two. but thats all it would take to make the car want to start, but it wont let the car fire properly.

Sorry..... 1 notch off is just not good enough. It has to be exact , then if it doesn't run start looking at other posibilities.
Remember that the camshaft turns twice eash time the crank turns once. The distributor rotor works off a gear on the cam.
Your rotor could be off a bit , or it could look exactly perfect the way it was when tou took it out , and still be 180 degrees off.
You have to get your engine to "top dead center" and make sure everything is the way it should be.
A timing chain ( or belt ) can cause permanent and fatal damage to the valve train and pistons in motors that are "interference engines" Find out weather yours is. In a non-interference engine , the clearance between the valves and the pistons is large enough to alow them to move out of time without crashing into each other. An interference engine is not so forgiving.
The fact that your engine cranks makes me hopefull that it is a non interference engine , and that damage has not been done.
Try to find a haynes manual for you vehicle , it will walk you through the steps for most repairs.
