Fuel Injector: Testing and Inspection

Checking Resistance Of The Fuel Injectors:

1. Disconnect the fuel injector electrical connectors.

2. Measure the resistance between the injector terminals for each injector.
Refer to SPECIFICATIONS/ELECTRICAL.

NOTE: Measuring the resistance for the injectors on the rear bank (# 2,# 4, and # 6) can be done through the injector connector.

Rear Bank Fuel Injector Connector For Turbo:

3. Disconnect the fuel injector electrical connector.

4. Measure the resistance between the injector terminals.
For injector # 2 connect an ohmmeter between the connector terminals # 1 and # 4.
For injector # 4 connect an ohmmeter between the connector terminals # 2 and # 5.
For injector # 6 connect an ohmmeter between the connector terminals # 3 and # 6.
Refer to SPECIFICATIONS/ELECTRICAL.

5. Reconnect the electrical connectors.
If the resistance is not within specifications, replace the injector(s).

FUEL INJECTION RESISTOR

Fuel Injector Resistor (DOHC-Turbo):

1. Disconnect the electrical connectors from the resistor.

Fuel Injector Resistor Test Points:

2. Measure the resistance from each terminal to terminal # 4.
Refer to SPECIFICATIONS/ELECTRICAL.
3. If the resistance is not within specification, replace the resistor.
