FUEL PUMP
RESISTORInspect the PGM-FI main relay
(seepage 11-120).
Engine will not start.
Inspection of fuel pump
resistor.
Disconnect the fuel pump resis-
tor connector.
Measure the voltage between
BLK/YEL (+) (on harness side)
and body ground (-) when the ig-
nition switch is first turned ON.
Is there battery voltage?
(for 2 seconds)
Turn the ignition switch OFF.
Install a jumper wire between
two terminals on the wire
harness side of fuel pump
resistor.
Turn the ignition switch to
START position.
Does the engine start?
Turn the ignition switch OFF.
Disconnect the C489 (6P) con-
nector (located behind the seat
back panels).
Replace the fuel pump resistor.

C489 CONNECTOR (6P)
Inspect the fuel pump (see page
11-119).
BLK/
RED (+)
Measure the voltage between
BLK/RED (+) (on wire harness
side of fuel pump) and body
ground when the ignition switch
is first turned ON.
Is there battery voltage?
(for 2 seconds)
Repair open in BLK/RED wire be-
tween the fuel pump resistor and
the fuel pump.
