This is a bad PCM. Try to disconnect the security system first and if it still does not start then it is the PCM.

What are the wire colors of the neutral safety switch on a 2000 Caravan 3.0 liter with a 4-speed automatic transmission.


Brown wire with yellow tracer shows to be wire color. You can always jump the starter to get it to crank, but, that doesn't mean it will start. In the past I have been lucky, different vehicle, I put the key in on position, jumped the starter relay, the vehicle started, I managed to get it home.
When testing, make sure tranny is in park or neutral and functional parking brake is set. There are safety issues, safety is your responsibility. You don't want the vehicle to move when your working on it.
You realize if you bypass anything, it may start in any gear, if it does it will run over you or one of the kids, anything that gets in the way. Again, safety for everybody is your responsibility.

Anon, possible security lock out or the safety neutral/park switch faulty, not plugged in, bad wire.

Will a van start without the steering column locked?


Do you mean it won't crank at all, or cranks but does not start. If the first, turn on headlamps and try to start. Do headlights dim? If not, you may have bad battery connections, bad solenoid, bad neutral safety switch. If lights dim, bad battery, connections, solenoid or starter motor.

Have a no crank 2000 grand caravan replaced starter I've check all wires under hood I've checked all fuses I've even checked all relays that pertain to shut down, starter , under hood and all relays u


Sounds like an electrical problem. The caravan has multiple safety cutouts that prevent the engine from starting. The ignition switch and the neutral selector switch are the two most likely to cause the starter not to turn. The function of these as well as the starter solenoid relay and the battery connections and such can be checked with a voltmeter. Grab a manual at your favorite local auto parts store and begin troubleshooting before you go and buy more parts you may not need.

Van wont start. no power


Maybe the starter or starter solenoid is bad. First, make sure connections at battery and starter are clean and tight. Old school method: turn headlights on, and (if good and bright) observe them while someone turns key to crank. If they dim noticeably and starter makes no sound, likely the starter has failed. If you observe no difference in headlight strength, then likely the starting circuit from ignition switch to starter solenoid is not working. You could take the wire off starter solenoid and see if it has power there while key is in crank position. If you do have power there, starter needs to be tested, or the solenoid is bad. If no power to the solenoid when cranking, then the circuit from the ignition switch to the solenoid will need diagnosing. Your neutral safety switch, and possibly a starter relay is in that circuit before it reaches the solenoid.
Good luck.

Starter won't engage


It's most likely the neutral safety switch. Try putting the shifter in Neutral and slipping it just a little toward Park and see if it'll crank. If it does the neutral safety switch is the problem but worn linkage is the cause.
You've already check or replace everything else so it has to be this or the ignition switch.

Same problem


Check your fuses for wipers and lights. If good use a volt meter and check power at the fuse. If your wipers, radio and dash lights worked before you changed the nuetral safety switch I would retrace my steps and make sure I didn't leave something disconnected. It happens a lot. Let me know what you find.

My 1997 dodge caravan won't start. has no power to starter wire or to engine. battery ok stater ok switch ok fuses and relays ok


there is an interrupt switch, called neutral safety switch. When it fails or goes out of adjustment, no start, and essentially no protest or indication. Try foot on brake, shift to neutral, turn key to start and slowly move shifter out of nuetral in each direction. If starter actuates, look into switch adjustment.
