starting issue on a KA24e

[Dori90]

im having starting problems with my ka. the car will turn over slowly and sometimes it will start. its just like if your battery is low then the car will turn over slowly..i check my battery and its fine and i checked the starter and its fine..its not the alternator because the battery light is not on..when i jump start the car it starts up..wat could be the problem..

what kinda voltage is the battery reading? And touch terminals of starter together with screwdriver while key is on and see if it still is slow. Have you actually taken out the starter and had it tested?

im going to get the battery check and the starter check...my battery is reading 12.5.. ..my car will start if i jump start it..when the car is running it reads 13.8..

so i got my battery tested and it failed..so it might be the battery..the starter passed
