[brokestudent]

So I have been puttering around in the truck no big issues decided to drive her a little further today. She died though at a place I've already made it to. Seemed like she was running out of gas going down the road then finally died. The oil pressure light came on and stayed on at the end right before she died, it had been flickering bit right before she died and flickeringa lot yesterday changed the oil pressure switch today was taking her out see if she still flickered which she didn't. I put gas in her still won't start. It's a 63 Chevy c 10 and I don't have a clue what's wrong with her right now. Also when pushing her I could heara clicking sound
