Answers :

Had similar problems last wk. turned out to be alternator. if its a 04 like mine check recalls on it.
Try this:
\012Make sure the positive cable, makes a good connection at the battery and at the starter. Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine.
  • Check the battery the simple way, like this:
  • \012
\012Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.
  • Check the starter and solenoid:
  • \012
\012If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
\012If the starter spins and no crank, the problem is most likely the Solenoid's bendix gear is stuck.
\012Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck bendix gear.\012
  • Make a simple test of the alternator:
  • \012
\012If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.
