Test NTC-3C - Checking Fuel Pressure

NOTE: Perform TEST NTC-3A before proceeding.

WARNING: High fuel pressure may be present in fuel lines. Open fuel system with caution. See FUEL PRESSURE RELEASE .

Using scan tool, stop ASD fuel system actuation. Release fuel pressure. Remove fuel pressure gauge.
Inspect fuel return line between engine and fuel tank for kinks or restrictions. If no kinks or restrictions exist on fuel return line, go to next step. If a kink or restriction exists in fuel return line, release fuel pressure and repair or replace fuel return line as necessary. Perform TEST VER-2A.
Disconnect fuel return line at fuel rail. Connect one end of a hose to fuel rail nipple in place of fuel return line. Place other end of hose into an approved 2 gallon fuel container. Turn ignition on. Using scan tool, actuate ASD fuel system. Observe fuel pressure gauge. If fuel pressure is 53 psi (3.7 kg/cm² ) or less, go to next step. If fuel pressure is more than 53 psi (3.7 kg/cm² ), release fuel pressure. Replace fuel pressure regulator. Perform TEST VER-2A.
Turn ignition off. Disconnect external hose at fuel rail. Reconnect fuel return line to fuel rail. Disconnect fuel return line at fuel tank. Put end of disconnected hose into an approved 2 gallon fuel container. Using scan tool, actuate ASD fuel system. Observe fuel pressure gauge. If fuel pressure is more than 53 psi (3.7 kg/cm² ), release fuel pressure. Repair fuel return line for a kink or restriction. Perform TEST VER-2A. If fuel pressure is 53 psi (3.7 kg/cm² ) or less, release fuel pressure. Repair or replace tank inlet strainer for a restriction. Perform TEST VER-2A.
