Relay Testing
- Remove the PGM-FI main relay. Relay is behind seat, on rear bulkhead. See BUZZERS, RELAYS & TIMERS
in COMPONENT LOCATIONS.
- Attach the battery positive terminal to the No. 3 terminal and the battery negative terminal to the No. 2 terminal of the PGM-FI main relay. Then check for continuity between the No. 5 terminal and No. 2 terminal of the PGM-FI main relay. See Fig 1
. If there is continuity, go on to next step. If there is no continuity, replace the relay and retest.
- Attach the battery positive terminal to the No. 4 terminal and the battery negative terminal to the No. 7 terminal of the PGM-FI main relay. Then check that there is continuity between the No. 3 terminal and No. 1 terminal of the PGM-FI main relay. If there is continuity, go on to next step. If there is no continuity, replace the relay and retest.
- Attach the battery positive terminal to the No. 1 terminal and battery negative terminal to the No. 2 terminal of the PGM-FI main relay. Then check that there is continuity between the No. 5 terminal and No. 2 terminal of the PGM-FI main relay. If there is no continuity, replace the relay and retest. If there is continuity, the relay is okay. For additional testing if the fuel pump still does not work, follow the flow charts. See Fig 2
