    Why does my starter turn slow

    Why does my starter turn slow after the car has been driven 10-20 min. When I try to restart the car after it sits for 5-10 mins. I turn the key it sounds like my battery is weak but it's fully charged. If I give it a little gas and turn the key it starts right up. If I let the car cool down a bit then it will start normally again.

    Usually after sitting overnight or long periods of time, there's no problem it starts right up.

    Would a bad igniton coil give me this problem?
    Or distributor?

    I don't think it's the alternator or battery because the battery is always charged.

    Thought it was the igniton switch and replaced it a few days ago but the problem is still there. Also replaced starter last year after old one died.

    Has anyone had this problem and fixed it?

    Heat from the engine could soak to the starter, making the internal tolerances too tight. A too tight starter could be harder to spin.

    The battery could also be bad if it boiled. When the starter is slow to crank, try to jump start the car, this will tell you if the problem comes from the battery of the starter.

    I don't have anybody to jump start the car. I can tell you that the battery is at 12.5 before driven using my multimeter. If the battery is boiled will the battery still hold a charge strong enough to start the car when it is warmed up? It seems kinda funny that if I turned the key and give it a a little gas at the same time it starts right up when it's warm. I bought the battery in Feb of this year but the date on the battery is Dec 2016.

    I did look at the part of the motor where the starter is attached and right next to where it's attached to the motor I see some black grease build up on the motor. Would that affect the starter because it might retain more heat in that area?

    There cars are old, there are many things that can go wrong with time.

    Slow cranking can be caused by this

    - Bad starter
    - Bad battery
    - Bad wires/connections
    - Hard to turn engine.

    Keep it simple. Check the wires and connections first. They might not be cable to carry enough current.

    If the battery is known to be good and test fine with a proper load test, check and make sure teh battery clamps are clean and tight , engine and chassis grounds are clean and tight .
    If the starter is pretty old , the brushes could be getting worn which will cause a slow crank fault.

    Yeah, check all the wires and connections first. Check grounds too.
