11. FUEL PUMP RELAY NO.2 CHECK
(1) Remove fuel pump relay No.2.
(2) Using jumper wires, connect fuel pump relay No.2 terminal
(3) to battery (+) terminal, and terminal (1) to battery
(–) terminal, respectively.
(3) Connecting and disconnecting the jumper wire on the
battery (–) terminal end, check for continuity across
terminal (2) and terminal (5), and across terminal (4) and
terminal (5), of fuel pump relay No.2.

(4) If the continuity is checked abnormally, replace fuel pump
relay No.2.
12.FUEL PUMP RESISTOR CHECK
(1) Disconnect the fuel pump resistor connector.
(2) Measure resistance across the terminals.
Standard value: 0.6 – 0.9 Ω
(3) If the measurement falls outside the specified range,
replace the fuel pump resistor.
