Keep in mind as you follow this video that there are differences in fuel system designs. Some fuel pressure regulators are in the fuel tank or are part of the fuel filter. While other systems use a variable speed fuel pump and have no fuel pressure regulator at all. Symptoms: intermittent long or extended cranking, start/stall condition, rich exhaust trouble codes (P0172, P0175), no start from a flooded condition (severe leak), fuel contaminated oil (severe leak) Fix:, replace the fuel pressure regulator, change the engine oil (possible fuel contamination) Testing procedures shown:, how to use fuel trim as a guide in finding a leaking fuel pressure regulator Tools used:, scanner (Solus Pro), Related videos: Leaking Fuel Pressure Regulator (symptoms and testing) https://youtu.be/6pb2jt8tabM GM CPI Leak Part 1 (bleed down testing) https://youtu.be/09_wQ9yQ85A GM CPI Leak (part 2) Regulator repair https://youtu.be/dAAFM3zlJME Playlists: (Chapters 14, 15,16) Fuel Delivery and Fuel Pressure Testing https://www.youtube.com/playlist?list=PLAFYVCyenqcrstVqfSc1PCbQ1pebuNIO6 For more information on this topic, I have written a “field manual” called Engine Performance Diagnostics which is available at www.scannerdanner.com as an eBook or paper book.
