Just purchased a barn find 94 dx sedan manual. Its been sitting outside for 10+ years. Paid a few hundred for it. Im no mechanic. Its sitting on 4 flats and dead battery. I tried to jump start, it just spins over. Fuel gauge says empty. It was a daily driver when parked and regular service was done. Gonna get new fuel today and starter fluid. What are best practices starting a project like this?
