The fuel pressure regulator on your 2002 Chevrolet Silverado is located on the fuel rail on the right side of the engine. I would not suspect a fuel pressure regulator to cause the no start condition you are having. I would recommend a more through diagnoses before replacing any parts.
Had same kind of problem. If you don't remember when the last time the fuel filter had been replaced and have not done so yet, do so. There's a very big difference of fuel flow between new filter and clogged filter.
how much does is cost normally to repair the fuel pressure regulator leaking gas on engine of a 2001 Hyunda
