I have a 2001 chrysler sebring lx wont turn over

It is probably a problem with the Anti-theft system. There are countless posts on FixYa with the same problem. Chrysler dealer indicates that locking and unlocking the doors three times with the remote will reset, however this did not work in my case.

Yea i had same problem with the fuse (start/fuel) replaced starter - OK no problem (bought used/rebuilt one at starter depot) 180 baks new -300 or so

There is a fuse in the under hood fuse box that will do that. its 20 amp start/fuel pump.

Hope you got a good deal on that oil change. do you believe in coincidence. I can't imagine how an oil change could do anything to stop the engine from starting. So you have to rule out things like starter and fuel pump. to check the fuel pump go to a parts store and buy a can of starter fluid. Remove the top pf the air cleaner box. Have someone spray starter fluid into the opening going to the engine while you are trying to start the motor. If it fires up the pump is bad if not go on to the starter. For the starter locate the relay under the hood (in a fuse box) labeled for the starter. Remove it. Then run a wire from the positive terminal of the battery (careful not to ground to car) and touch where the relay plugged in. One of the points should kick the starter over. If none of them do i would suspect the starter. if all is ok the next possible suspect is the computer. You will need a dealer for this one but some computers have extended warranties because of problems so ask the dealer about it. I just had one replaced for a customer last summer on a 2001 Chrysler T&C and it was covered under warranty. Whole visit was around $200 If this helps please reply and good luck
