Car will start sometimes but the will hear a single click at the relay when it won't. The starter is not engaging. I cleaned battery and tested 12 volts, fuse is OK and tests 12 volts when starting but nothing at failure. I replaced ignition switch because I had an extra checked basic groundsand want to test starter but I can't find it anywhere! I checked kia info and it says right beside tranny on passenger side but I don't see it and can't vet to it. Does anyone have a picture?
