2003 PT cruiser with turbo

My camshaft sensor went out then got it replaced
and the car still there will not turn over I've already
had the computer reset at Chrysler prior to this any
ideas on what could be wrong I really need my car
both my children are disabled and I need to get
them back-and-forth the therapies in the car only
has 100,000 miles on it I've owned it since the
beginning  
So to re-clarify I have had the sensor go out three
times this is the third time that it's gone I'll put it
actually shut down and left me stranded on the side
of the road with my children who both have
disabilities so I imagine that it was not fun but I
have the computer reset two years ago because I
was having some other issues and now they
replaced it fixed it the check engine light is not on
but the car will not turn over any ideas
