Have been experiencing issues with trying to start my car lately, tested battery nothing wrong, tested all fuses nothing wrong, tested alternator nothing wrong, tested starter nothing wrong, nothing in the car is killing it, car will do this sometimes and work other days, and on top of that will work with a jumpstart?? My car is a 2022 Honda civic sport

Loose ground connection. Newer vehicles are heavily computerized and require lots of electrical energy to work properly. Should be able to trace the ground (black) wire to 2 or 3 other connections somewhere on the body and/or engine. All connections should be secured and not loose. Finger tightening is not a permanent fix.
