Cut-Off Relay
- With ignition switch off, remove dashboard under cover and pull down fuse box panel mounting bolt and nut. Remove fuel pump cut-off relay.
- Check for continuity between No. 3 terminal and body ground. Continuity should exist. If there is no continuity, check Black wire.
- Attach positive probe of voltmeter to No. 2 terminal and negative probe to No. 3 terminal. Then turn ignition switch "ON". Battery voltage should exist. If not, check Black/Yellow wire from ignition switch and fuel cut-off relay as well as No. 1 fuse (15 Amp).
- Turn ignition switch "OFF". Attach positive probe of voltmeter to No. 4 terminal and negative probe to No. 3 terminal. Then turn ignition switch "ON". Battery voltage should exist. If not, check Blue wire from ignition coil and fuel cut-off relay.
- Turn ignition switch "OFF". Connect jumper wire between No. 1 terminal and No. 2 terminal. Turn ignition "ON". The fuel pump should run. If not, check Yellow wire between fuel pump and fuel cut-off relay, and check Black wire from fuel pump to ground. If wires are OK, replace fuel cut-off relay and retest.
