Ignition switch problem 2000 town and country 1. Starter wont engage 2. will start and run if I remove switch and the electrical switch and turn the the ignition block with screwdriver 3 Had locksmith clean the key switch

First make sure your battery is fully charged and in good condition. Have you ever replaced the battery?
'If the battery is Ok then it likely is a Starter motor or solenoid, reasonably inexpensive fix for an experienced mechanic. When it happened to me I had an auto-electric shop install a rebuilt starter.

bad battery will light lights but fails when the starter is engaged --have it load tested
starter relay or ignition switch could also be faulty

THERE IS A STARTER RELAY IF THERE IS POWER TO STARTER, GETTING CRAKE? BUT NO FUEL, DOESN'T TURN OVER?

have a load test done on the battery
have the charging system properly checked by an auto electrician

First thing to look at is the ignition switch starter contacts as it seems the contacts need a bit of coaxing to make. If they prove to not be a problem the next thing to look at would be the starter solenoid and then the starter itself.

Here's a copy of a service bulletin on your problem.

I'll bet the dealer says $300 for parts and 2 hrs labor.:screwy:
