Sounds like the battery is just dead…? How old is the battery?

False alarm turns out it was a battery issue. strange thing is we tested the battery and its reading ok, even has the little green indicator.
But does not hold a charge. As soon as i swapped in the new battery car starts and works fine.

Yeah, it sounded pretty cut and dried so that’s why I suggested the battery. Glad to hear that’s all it was! 👍

I had a similar situation with an Alfa Romeo Giulia we owned a couple of years back. The battery supposedly was charged, but the instant you put any load on it, it acted dead. Replaced the battery and all was well.
