FUEL SYSTEM (Programmed Fuel Injection)
6-63
COIL LINE INSPECTION
Turn the ignition switch OFF.
Disconnect the bank angle sensor 6P (Black) con-
nector.
Turn the ignition switch "ON".
Measure the voltage between the engine stop relay
connector of the wire harness side and ground.
If the battery voltage appears, the engine stop relay
coil line is normal.
If the battery voltage does not appear, inspect the
following:
– Open circuit in Black wire between the fuse box
and engine stop relay coil line side
– Open circuit in Red/Orange wire between the
engine stop relay and ECM
– Inspect the engine stop relay continuity (page 6-
64)
FUEL PUMP RELAY
REMOVAL/INSTALLATION
Remove the front center cover (page 3-4).
Remove the fuel pump relay from the relay connec-
tor.
Installation is in the reverse order of removal.
OPERATION INSPECTION
Remove the front center cover (page 3-4).
Turn the ignition switch "ON".
The fuel pump relay coil is normal if the fuel pump
relay clicks.
If you hear the fuel pump relay "CLICK", but fuel
pump does not operate for a few seconds, inspect
the following:
– Fuel pump relay continuity inspection (page 6-
64)
– Fuel pump relay switch line inspection (page 6-
64)
• If the above inspections are normal, replace the
fuel pump with a new one, and recheck.
If you do not hear the relay "CLICK", inspect the fol-
lowing:
– Fuel pump relay coil line (page 6-65)
– Fuel pump relay continuity inspection (page 6-
64)
• if the above inspections are normal, Inspect the
ECM power/ground line (page 6-19).
