So when I bought this car, I had problems with my starter at first because I had a slight oil leak so I changed my starter and it worked for a while until my oil leak got worse and I thought it was the oil pressure sensor so I changed that and that didn’t fix it so I changed the entire oil cooler and since then my car is getting no electrical power whatsoever unless it’s hooked up to another running vehicle through jumper cables. When I try to start it it clicks, I hear the starter engage, but no turnover. What other electrical component could cause my car to be getting no power not even to the power locks or headlights.
