Electrical Test
When depressing the START/RER button, the fuel
pump should run for 2 seconds to build up the
pressure in the system.
If the pump does not work, disconnect the plug
connector from the fuel pump.
Install a temporary connector to the fuel pump
connector. Apply 12 V (+) on pin 2 and (–)onpin
1 to this test harness.
If pump does not run, replace the fuel pump mod-
ule.
Otherwise, probe pin 2 and battery ground of fuel
pump connector on vehicle harness side. When
depressing the START/RER button, you should
read battery voltage for approximately 2 seconds
(then, the voltage will drop). If battery voltage
does not appear, the problem can be in fuse, re-
lay(s), harness or in fuel pump connector. Repair
or replace appropriate part.
Check continuity between pin 1 of the fuel pump
connector on the vehicle harness side and termi-
nal 29 of the ECM connector B. If there is no con-
tinuity the problem is in the harness. Otherwise,
