Question1998 stratus won't start. just clicks. when does start runs and drives fine. doesn't do it all the time. no check engine light.
AnswerHi Dick,
A soft click coming from the power distribution box under the hood is the sound of the starter relay. It proves that the ignition switch and park/neutral safety switch are working. A louder click from the underside of the engine also proves that the connection from the relay to the starter solenoid is working. So in most cases, a loud click means that the only reason the engine won't reliably crank is that:
1 the battery is too weak to activate the starter motor, or
2 the starter motor armature/brushes/windings are compromised and the motor needs to be rebuilt/replaced, or
3 the cable that connects the battery to the starter motor is loose/corroded/compromised at one end or the other.
You can remove the - post clamp at the battery (for reasons of electrical safety) and verify whether or not 3 is the problem. Then reconnect the - post clamp.
You can check 1 by checking the charge level of the electrolyte in the battery with an hygrometer, or by considering how old it is relative to its warranty life.
If you satisfy yourself that 1 and 3 are not the cause then it is time to remove and either get the motor rebuilt or trade it in for a rebuilt motor. I prefer doing the former it the motor is the one that came with the vehicle.
That is how I approach such a situation.
Please let me know if something else comes to light or you have a further question.
