warm starting issues

[bmohr]

Hello. I've searched this board for similar issues, but couldn't find any. Ever since purchase the car cranks very slowly after I drive it and stop for errands or whatnot. Now, it's never NOT started after a long drive. BUT it seems so weak it scares the crap out of me. Anyone have this issue, or any advice troubleshooting this thing? Any help is MUCH appreciated! Thanks in advance!

How old is your battery?

If it is 4 years or older it likely needs replacing. Start there.

If you are positive the battery is good then measure the charging voltage when the engine is running - it should be close to 14 volts.

If the battery is tested and found to be sound then measure the amp draw of the starter when hot.

I had the same issue with my car. The car would start just fine when it was cold but after it warmed up it cranked real slow. It got worst after a while to the point that it wouldn’t crank unless I let it cool down for a few minutes. Turned out it was the starter that was bad.

Thanks for the advice. Yes..the battery was diagnosed "good" and the amp meter reads 14. Everything normal but the slow crank after engine is warm. Seems to be getting a little weaker as time goes by. I'll have my tech look at the starter. How much was yours to replace? Or did you do it yourself? Thanks for the advice! This issue was starting to worry me.
