Fuel Supply System
Fuel Pump Resistor
Troubleshooting Flowchart
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)
Inspect the main relay (page
11-104)
Turn the ignition switch OFF.
FUEL PUMP
RESISTOR
JUMPER WIRE
Replace fuel pump resistor.
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 fuel pump con-
nector.

(From page 11-106)
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.
Inspect the fuel pump
