NTC-5A: Checking Fuel Delivery/Pressure

WARNING: Fuel system is under high pressure. ALWAYS release fuel pressure before attempting to open system for testing or component replacement. See FUEL PRESSURE RELEASE. DO NOT allow fuel to flow onto engine or electrical parts while testing fuel system components.
  1. Turn ignition off. Inspect fuel lines for leaks, kinks or restrictions. Release fuel pressure and repair or replace fuel lines as necessary. Perform TEST VER-2A. If fuel lines are okay, go to next step.
  2. Release fuel pressure. Connect fuel pressure gauge to fuel pressure test port. Using scan tool, actuate fuel system test and note fuel pressure. Fuel pressure should be 44.2-54.2 psi (3.23-3.96 kg/cm2 ). If fuel pressure is within specification, test is complete. If fuel pressure is not within specification, release fuel pressure and replace fuel pump module. Fuel pump module is located in fuel tank. Perform TEST VER-2A.
