To check fuel pressure you need a special adapter that goes in between the fuel rail on the engine and the fuel supply line from the pump. I would check the fuel filter. Not very expensive and probably needs one any way. The only "dry gas" products that remove water have alcohol in them. Too much alcohol and it will run lean. I don't recall the cavalier having E85 capability back then. Most of the time the pump either works or it doesn't. That being said I had a 07 Avalanche today with a lack of fuel problem.

A clogged catalytic converter won't make it buck. It will just be a real turd.
