Checking components and wiring: Notes

Check the resistance of the injector between terminals 1 and 2.

Check the cable between injector terminal 2 and control module:

terminal #A16 (#A16) (ECM 2310)
terminal #A34 (#A34) (ECM 2320)
terminal #A15 (#A15) (ECM 2330)
terminal #A33(#A33) (ECM 2340)
terminal #A14 (#A14) (ECM 2350).

Check the power supply between system relay terminal 3 and injector terminal 1. Check for an open-circuit.

Remedy as necessary.
