Fuel Pumps
Chevy Beretta
Ford Ranger XLT

Your 1990 Beretta was running fairly well until you added octane booster to a full tank of gas because it had been sitting for almost a year Now it starts and immediately dies If you hit the throttle?

If it idles ok and then dies when you try to accelerate, I'd check the fuel filter first - easiest and cheapest. If that doesn't check out, then it might be the fuel pump or the fuel regulator.
