1. 1

   Injector resistance

2. 2

   Wiring harness resistance

3. 3

   Connection integrity of the injector and wiring harness

1. 1

   Measure the resistance of the injector

   Use a multimeter to measure the resistance of the injector and compare it to the specifications provided in the service manual.

2. 2

   Measure the resistance of the wiring harness

   Use a multimeter to measure the resistance of the wiring harness connected to the injector and compare it to the specifications provided in the service manual.

3. 3

   Inspect the connections

   Check the connections between the injector and the wiring harness for any signs of damage, corrosion, or poor contact.
