1. 1

   Inspect the wiring harness running from the Engine ECU to fuel injector No. 6 for chafing, melted insulation, or pinched wires

2. 2

   Disconnect the plug at injector No. 6 and check for corrosion, bent pins, or moisture inside the connector

3. 3

   Use a multimeter to test the injector harness for continuity, verifying there is no open circuit, no short to ground (earth), and no short between the two injector wires

4. 4

   Measure the resistance across the pins of injector No. 6 itself to check for an internal open or short in the injector coil
