Test NTC-5B: Checking Fuel Delivery

NOTE: Perform TEST NTC-5A  before proceeding.
WARNING: High fuel pressure may be present in fuel lines. Open fuel system with caution. See FUEL SYSTEM PRESSURE RELEASE .
  1. Using scan tool, stop ASD fuel system actuation. Apply parking brake. Place shift lever in Neutral. Start engine. While monitoring fuel pressure gauge, momentarily snap throttle wide open increasing engine speed to more than 3000 RPM.
  2. If fuel pressure did not drop to less than 35 psi (241 kPa) at all, fuel pressure is normal. Test is complete. If fuel pressure dropped to less than 35 psi (241 kPa) at all, go to next step.
  3. Place shift lever in Park. Turn ignition off. Inspect chassis fuel supply line for kinks or restrictions. If no kinks or restrictions exist in chassis fuel supply line, go to next step. If a kink or restriction exists in chassis fuel supply line, release fuel pressure and repair or replace chassis fuel supply line as necessary. Perform TEST VER-2A .
  4. Release fuel pressure. Remove fuel pressure gauge. Remove fuel filter. Inspect fuel filter for restriction. If fuel filter is restricted, replace fuel filter. Perform TEST VER-2A . If fuel filter is not restricted, replace fuel pump and fuel filter. Perform TEST VER-2A .
