Car drove great. Went into shops. Then no start. Tried to jump start from jump pack but no go. Pushed the car and it started. Driving home engine light and alt light on. Changed starter motor but just clicks. Tried jumper leads still no go
Jumped it by towing it startered. Battery tested ok. New starter motor. Fuses look all good?????
