If it does not read 12 V, check the corresponding
fuse(s), relay and continuity of circuit. If continuity
is faulty, repair wiring harness.
Resistance Test
Disconnect the injector from the wiring harness
and check the resistance of the injector itself.
The resistance should be around 14.5
.
If resistance value is incorrect, replace the injector.
Reconnect the injector and disconnect the con-
nector A from the ECM as well as the engine/
vehicle connector.
Using a multimeter, check resistance value be-
tween terminals as shown in the table below.

If resistance value is correct, check wiring of cor-
responding relay. If good, try a new ECM. Refer
to ECM REPLACEMENT procedures elsewhere in
this section.
If resistance value is incorrect, repair the wiring
harness/connectors or replace the wiring harness
between ECM connector and fuel injector.
Fuel Injector Replacement
Removal
Release the fuel pressure in the system using
B.U.D.S. Look in the Activation tab.
Disconnect fuel hose at the connector.
Wrap a rag around the hose end to prevent rail
draining.
