Test Step 3. Test Rear Fuel Injector
Harness Under Valve Cover.
1. Turn OFF the ignition and battery
disconnect switch.
2. Remove valve cover and rear fuel
injector harness (WP 0103) from
fuel injector #5.
3. Install a jumper wire at fuel injec-
tor #5 between terminal 1 and ter-
minal 2 (WP 0009, Figure 10) of
rear fuel injector harness.
4. Using a digital multimeter, test for
Continuity - (Resistance should be
