My 2000 Dodge Grand Caravan will crank but won't start.

There is no fuel reset button. If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure, Also, check fuel injector pulse. Are there any applicable trouble codes?

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.

fuel pump, check for fuel pressure

Alternator sounds like check to see if it is sending a charge

put a fuel gauge on the system and see if the fuel pressure bleeds down

Spray some carburetor into the throttle bore into the engine ,does it start ? pull a plug wire an hold near ground - metal on the engine ,crank it over , is there spark ? Hook up a fuel pressure gauge tet for fuel pressure . Quit guessing as to what the problem is . Learn how to test or take it to a qualified repair shop .
How to Diagnose an Engine that Turns Over and Cranks But Does Not Start...

Check the neutral safety switch on the transmission. It should have three wires on the connector (if I remember correctly). There should be power on the Brown with yellow wire with the key in the crank position. If there is ground that wire and see if the van starts. If it does replace the switch. If it does not check the starter relay. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

try checking the crank shaft sensor, i had that problem with a 95 cirrus

sounds to me like a siezed up ac unit.. it would not spin while all other pulleys spin... thus causing the broken belt.. hope that helps you
