My car starts and stops immediately since i change the crankshaft sensor n i put in gas then drove 7miles 2 another town n stop the car n that,s when it happen.

Sounds like your VATSS system is engaged. You say that you changed steering columns, did you switch the lock cylinder so you still use the original key? You have to have the same chip as the original to the car or your anti theft system will engage.

Do you have any codes?tune up,fuel filter,crankshaft sensor.Sometimes new battery is not good it happen to me.

You need to provide your driver habits, any check engine light issues. Exactly how many miles to the gallon are you getting in town, freeway and combined?

clean throttle body,could be crankshaft sensor.

I Love my Chryslers and now own a 2000 300m. What happens when mechanics plug in an OBD II tester they suggest where the problem is.On my 2000 Town & Country 3.8L I trusted two separate dealers. First time, the van stopped dead on a busy Hot summer afternoon. They replaced the cam sensor and $250 later it still wasn't fixed.The next dealer said it was the crankshaft sensor drove away after the repair and another $250 it stalled a mile down the road.I fought with it for a day and thought through the process. I had Fuel ,Air intake, and spark. However the engine wouldn't breathe due to a plugged PCV valve. My local auto parts supplier sold them for $3.99. Changed it in the parking lot in 3 minutes. I drove off and it never stalled again.This I suspect is also the problem you are experiencing.Hope this helps,Good luck.

Have you had it to a shop that has a professional type scan tool that can view engine sensor data parameters ? Do you know what those are ? Idle air control counts , mass air flow sensor data , MAP sensor , TPS - throttle position sensor , crankshaft position sensors , Cam sensors , engine coolant temp , intake air temp etc......

so , you ran it out of gas after it sat for a while.
the question is .... what?
where do you put the gas in ?

Sounds like you have moisture getting into your ignition somewhere. Have your mechanic look at it again but have him water down engine compartment, little at a time.

no you just need to remove the timing belts and crank gear all can be done in car i am a kia master certified technician and have replaced a few of these on both v6 and 4 cyl

Maybe. But it could be the crankshaft position sensor or other sensor problem. Get it scanned for a trouble code.
