Test NTC-3A - Checking Fuel Pressure
WARNING:
High fuel pressure may be present in fuel lines. Open fuel system with caution. See FUEL PRESSURE RELEASE .
- Turn ignition off. Release fuel pressure. Connect fuel pressure gauge to fuel rail. Turn ignition on. Go to next step.
- Using scan tool, actuate fuel system test. If fuel pressure is 45-55 psi (3.2-3.9 kg/cm2 ), fuel pressure is normal. Test passed. If fuel pressure is not as specified, go to next step.
- Record fuel pressure reading. If fuel pressure is more than 55 psi (3.9 kg/cm2 ), go to step 5). If fuel pressure is less than 55 psi (3.2 kg/cm2 ), go to next step.
- Using scan tool, stop actuation test. Turn ignition off. Inspect fuel lines for kinks or restrictions. Release fuel pressure and repair fuel lines as necessary, and perform TEST VER-2A . If no kinked or restricted lines exist, go to next step.
- Start engine and note fuel pressure gauge reading. If fuel pressure is 44.2-54.2 psi (3.1-3.8 kg/cm2 ) fuel pressure is normal. Test passed. If fuel pressure is not as specified, go to next step.
- If fuel pressure is more than 54.2 psi (3.8 kg/cm2 ), fuel pump is okay, but internal fuel regulator is defective. Replace fuel pump module and perform TEST VER-2A . If fuel pressure is more than zero, but less than 44.2 psi (3.1 kg/cm2 ), replace fuel pump module and perform TEST VER-2A. If fuel pressure is zero, perform TEST TC-101A .
