Diagnostic Aids
Water or foreign material in fuel can cause a no-start condition during freezing weather. Engine may start after 5-6 minutes in a heated shop. Problem may not reoccur until vehicle is parked overnight in freezing temperatures. Ensure connections are not contaminated, corroded or damaged.
Low fuel pressure can result in very lean air/fuel ratio. Fouled or damaged spark plugs will also cause "engine cranks but will not run" condition.
