Checking wiring and connectors

Check the injector connector. Check for contact resistance and oxidation. Check for loose connections.

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 for an intermittent open-circuit.
