B5: Check Injector Feed Continuity

Remove relay PI Main
Measure the resistance between pin 5 PI Main relay socket, and in turn, the injector connectors: IJ003/002, IJ004/002, IJ005/002, IJ006/002, IJ007/002, IJ008/002, IJ009/002, IJ0010/002

- Is the resistance > 0.5 ohms?
Yes
GO to B6 B6: Check Fuse to Relay Continuity
Do not replace relay
No
Inspect the harness between the appropriate connector, splices PIS02, IJS01 or IJS02, PI002/005 and pin 5 PI Main relay socket. Repair as necessary and test the system for normal operation.
