2001 Chevrolet Silverado 1500 Question: Hard start



usda, 5.3L V8, Monterey, CA, July 30, 2010, 15:26

When starting my truck it often takes two or three attempts. It kicks over but does not fire. It runs great and theres no knocking and the gas mileage is great. I've change fuel filter, air filter, and ran a fuel injector cleaner through the system several times. Any hints? or tips?

    you need to check fuel pressure when it wont start. it may be the pump not retaining residual pressure for initial start.
