I have a 2004 Concorde (153.000) 3.5 Lxi
Two weeks ago I stopped to get gas got back in the car and it wouldn't turn over. Sat for about ten minutes and it started right up. Three days later I go out it starts right up go to eat breakfast come out and it won't turnover got a jump it starts right up. Next morning the battery tested bad and had it replaced. Six days later it starts up fine all week I stop for gas come back out and it won't turnover again I jump it and it starts right up and runs great for the next four days and the process repeats itself . Is this a possible starter or selinoid issue? Or something more?

 

when u say it wont start up what does it do sounds? single clunk nothing red dot on dash need details besides wont start.

 

It's trying to turnover and it just won't. As soon as I hook the jumper cables on it it turns over and starts. Battery and alternator test fine.

 

When I tested the battery .....had a surface charge on the battery I was told to let it sit for about four hours then turn on the lights for five minutes to get rid of the surface charge. Did that a couple of days ago and it starts every time. If it holds to form one day this weekend it will try and start it will crank but just not turnover.

 

As soon as I hook the jumper cables on it it turns over and starts

that is not a starter that is a battery issue if u drove it over to have it checked out yes the battery will show good because it was charged up by the alternator.

 

Does it just "click" when you try to start, then after a few tries starts right up?
If so starter solenoid contacts are suspect.

Doesn't click I can hear it cranking just won't turn over. It may be they sold me a bad battery or something is draining the battery. A mechanic said it sounds like a cam sensor or crank shaft sensor does either of those sound feasible?

 

ok now your changing your story again.
I think u need to let a professional take a look at it and fix it
