It probably needs shims added or subtracted to it. the wrong amount of shims will make it start hard
you need a new starter motor,
A way to tell is by the sound the motor makes. If it is winding slowly with no force it could be going out. If it skips or whines without action it is out.
1. engine won't start. 2. All you get is a click when you turn the key. (make sure that you have a good battery) 3. You hear a whirring sound but the engine does not crank. (the starter motor turns but the bendix does not engauge. 4. You hear this gosh awful screaming sound. (the starter spins but does not engauge the flywheel completely.) Probably a lot more but these have happened to me over the years. You can take the starter off (if you are mechanically inclined) and some auto parts stores will test them for you. Auto Zone does where I live.
It is likely to be the starter is not working.
fuel pump, and or starter
Battery dying - there isn't enough power left in the battery to turn the motor over during the starting process. Could also be the starter selenoid or the starter motor itself.
It depends if the starter is turning the engine over and its not starting the problem is not with the starter its with your ignition or fuel system most likely, If your start is making a whirring sound then its not making contact with the flywheel and you probably need a new starter
No, usually a scraping sound indicates the starter is dragging and needs to be replaced.
A starter will seldom "go bad", but when it does, you will definitely hear a "grinding" or "dragging" noise as it rotates (usually is slow to rotate). That condition is called "starter dragging", caused by worn bushings. When the bushings wear, the starter will drag against the armature inside the starter hull, causing the slow rotation and "dragging" or "grinding" sound. A single click when you try to start the vehicle is usually indicative of a faulty starter relay/solenoid. Or possibly just a loose cable. A rapid clicking sound is usually caused by a low battery. Could also be caused by a loose cale.

1. Dead battery 2. CPS is bad and needs to be replaced 3. Bad starter motor Hard to tell unless you can give more details, does it make a sound when you try and turn it over? A classic dead battery sound on Mercedes is a click noise when you try and start it, sometimes it confuses people and they think the starter motor is bad but that's not the case. I had a similar problem and it turned out that the grounding strap on the starter motor just disintegrated.
dead battery bad starter solenoid bad starter loose or corroded battery or starter cables
the motor is ether frose up, the starter is burnt up or ether it is not engageing
the starter cellanoid needs replaced.
Not enough power to starter motor.
fit a new starter motor ! simples ... next!

Sounds like your starter needs to come off and go for bench testing at a local auto parts that offers free testing (Autozone, Advance, etc.)Unfortunately, it does sound like your starter is one of the rare ones that is failing.See "Related Questions" below for more
