2000 dodge caravan.2.4 died pulling into a parking space..won't start again...motor turns over...just won't start...behaves like timing belt broke but belt is just fine...

Are you saying the engine will not crank, or crank but will not start ?
None of the engine sensors come into play until after the engine is cranking.
Cranking problems can include the neutral safety switch and other factors with the crank circuit back to the key switch.

Sounds similar to my old 94 dodge ram. Battery died at least I thought, replaced it and truck would not turn over. After about three hours of playing around I start checking all my wires and connections any loose wires I tighten or replaced if they looked worn or bad. And I found a ground wire was not connected to frame it came loose. Tightened it and hooked battery up and it started.

check steering wheel make sure horn buttons are not stuck

It sounds like the ignition switch went bad or the connection to the switch is bad

Make sure the transmission range selector switch is adjusted correctly it is the switch just below the shift cable post. Also try to start it in Neutral rather than park position.

call autozone for a price on it, they can tell you if it is replaceable

im going to say the starter is shot

Have you checked to see if all of the fuses are good? That could be the cause for the radio and the tripometer not working.

If it runs down highway fine, but just stalls when off throttle, turning, heater on, etc., I'd pull I.A.C. motor off and clean with throttle body cleaner & retry it. Clean port it came out of at same time too. if it cures it even temporarily, and does it again, replace IAC motor.

sounds like the alternator has stopped charging or has bad connection at battery
