The last couple of times I have tried to start the 04 CS, it turns over once quickly, then nothing. Then I return key to original position, try again and it starts. No warning lights on dash. All accessories functioning.

Is this the beginning of battery failure?

 

Starter, especially if it has been drowned in coolant post pipe failure.

Fuel pump relay, since that is another common one.

 

Oh boy. That might give some explanation to the coolant level warning I got yesterday, that was not there on re-start later in the day.

 

Coolant doesn't evaporate/disappear despite whichever expert says it does (I lost a LOT of coolant before the light came on). I have had this problem twice in one year, once was engine failure second time was the pipes (getting fixed now). It does also f up your starter, mine has been making all sorts of cool grinding sounds of late. Get it pressured checked before it gets worse.

Also coolant makes a nasty mess: It took me a year to get the coolant off my driveway the first time and it messed it up again and it's next to impossible to get off. Save yourself trouble before she blows.

Replaced it after it was making grinding noises and wouldn't start up from the first/second try at least 5 times.
