2001 Chevy Silverado 2500 HD 6.6l Duramax Pickup decided to not start one day! Pickup has alittle under 200,000 miles on it.. recently had a Fast Fuel system, new C3 pump, new fuel pressure regulator, and still wont fire on its own unless u give it alittle shot of fluid then she takes right off and runs great. I believe its got to be the FPRV thats only thing thats hasnt been changed I lost interest and want gone my loss ur gain
