- Ensure ignition is off. Disconnect electrical connector at fuel injector. Using ohmmeter, check resistance between electrical terminals on fuel injector. Replace fuel injector if resistance is not within specification. See FUEL INJECTOR RESISTANCE SPECIFICATIONS table.
- To check fuel injector spray pattern and volume, remove fuel injector. See REMOVE/INSTALL/OVERHAUL article. Disconnect fuel hose from fuel filter outlet. Use Delivery Hose (09268-41046) to install fuel injector between fuel filter and pressure regulator. See Fig 1.
- Place fuel injector into a clean graduated container. Place vinyl tube on end of fuel injector to prevent fuel spillage.
- Use scan tester to operate the fuel pump or apply battery voltage to electric fuel pump to pressurize the fuel system. See FUEL PRESSURE in BASIC TESTING - 2.7L article.
- Connect Fuel Injector Tester (09842-30070) to fuel injector for 15 seconds. See Fig 2. Measure fuel injector volume and check spray pattern. Test each fuel injector 2-3 times. Replace fuel injector if fuel injector volume is not within specification. See FUEL INJECTOR VOLUME SPECIFICATIONS table.NOTE: Ensure difference between fuel injector volume on all fuel injectors is within specification. See FUEL INJECTOR VOLUME SPECIFICATIONS table.
- Disconnect fuel injector tester. Ensure fuel leakage from end of fuel injector is one drop or less in specified time. See FUEL INJECTOR LEAKAGE SPECIFICATIONS table. Replace fuel injector if leakage exceeds specified amount.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
