Car won't start without being jumped
Hello. I have a recently restored 69 Camaro. My issue is that after the winter I went to start the car and it wouldn't start. I jump started it with a battery charger, and it ran and drove fine. However, even after driving around for 5-10 minutes if I stalled or stopped the car it won't start again. Last night I put a full charge on the battery, disconnected it, and today with a full battery charge tried to start her... and got nothing. I have a new (rebuilt) externally regulated alternator and the voltage regulator is new as well. Last fall when I completed the project this problem didn't happen. The battery is an Optima which I was told never went bad. I am going to jump start and drive her to AutoZone to test the battery and alternator, but thought I'd see if you guys had any ideas. Thanks!
