Information:


Electrical shock hazard. The electronic unit injector system uses 90-120 volts.
Turn the keyswitch to the OFF position.
Remove electrical power from the engine ECM.
Disconnect the valve cover connector for the injector harness.
Restore electrical power to the engine ECM.
Turn the keyswitch to the ON position.
Perform the "Injector Solenoid Test" at least two times.Expected Result:All of the cylinders indicate "Open" on Cat ET.Results:
OK - All cylinders indicate "Open" on Cat ET. The harness between the ECM and the valve cover connector does not have a short circuit. Proceed to Test Step 7.
Not OK - One or more cylinders indicate "Short" on Cat ET. Note the cylinders that indicate "Short". Proceed to Test Step 8.Test Step 7. Check the Injector Harness Under the Valve Cover for an Open Circuit or for a Short Circuit
Electrical shock hazard. The electronic unit injector system uses 90-120 volts.
Turn the keyswitch to the OFF position.
Remove electrical power from the engine ECM.
Remove the valve cover in order to gain access to the suspect injector.
Disconnect the harness connector from the suspect injector.

Connector terminals for the injector solenoid
Thoroughly clean the terminals on the injector solenoid and on the harness connector.
Use a jumper wire to short circuit the connector terminals on the harness connector for the suspect injector. This will effectively replace the injector solenoid with a short circuit.
Restore electrical power to the engine ECM.
Turn the keyswitch to the ON position.
Perform the "Injector Solenoid Test" at least two times.Note: The injector solenoid that shares the supply wire of the injector that is short circuited may indicate a false test result. Disregard this test result.
Turn the keyswitch to the OFF position.
Remove electrical power from the engine ECM.
Remove the jumper wire from the harness connector for the suspect injector. This will effectively replace the injector solenoid with an open circuit.
Restore electrical power to the engine ECM.
Turn the keyswitch to the ON position.
Perform the "Injector Solenoid Test" at least two times.
Turn the keyswitch to the OFF position.
Remove electrical power from the engine ECM.Expected Result:Cat ET displays "Short" for the cylinder with the jumper wire that is inserted into the harness connector. Cat ET displays "Open" when the jumper wire is removed from the harness connector.Results:
OK - Cat ET displays the correct status during the test. The harness wiring is OK.Repair: Use a multimeter to check the resistance of the suspect injector solenoid.The correct resistance of each injector solenoid is 1.06 0.05 Ohms.If the resistance of the solenoid is not within specifications, replace the faulty injector. If the four digit code that is stamped on the new injector is different from the four digit code that is stamped on the original injector, enter the new code into the ECM. Verify that the problem is resolved.If the resistance of the solenoid is within specifications the problem may be intermittent. If the problem is intermittent, refer to Troubleshooting, "Electrical Connectors - Inspect". Verify that the repair eliminates the problem.STOP
Not OK - Cat ET did not display the correct status during the test. There is a
