(b) Disconnect the fuel pump connector.
(c) Remove the O-ring from the fuel filter.
INSPECTION
1. INSPECT FUEL PUMP
(a) Check the fuel pump resistance.
(1) Measure the resistance between terminals 1
and 2.
Standard resistance:
0.2 to 3.0
at 20C (68F)
If the result is not as specified, replace the fuel
pump.
(b) Check fuel pump operation.
(1) Apply battery voltage to terminals 1 and 2.
Check that the pump operates.
NOTICE:
• These tests must be completed within 10
seconds to prevent the coil from burning
out.
• Keep the fuel pump as far away from the
battery as possible.
• Always the voltage on and off on the
battery side, not the fuel pump side.

ON-VEHICLE INSPECTION
1. CHECK IGNITION COIL ASSEMBLY AND PERFORM
SPARK TEST
NOTICE:
In this section, the terms "cold" and "hot" refer to
the temperature of the coils. "Cold" means
approximately -10 to 50
C (14 to 122F). "Hot" means
approximately 50 to 100
C (122 to 212F).
(a) Check the DTCs.
NOTICE:
If a DTC is present, perform troubleshooting in
accordance with the procedure for that DTC.
(b) Check that sparks occur.
(1) Remove the No. 1 engine cover.
(2) Remove the bolt and ignition coil.
(3) Using a 16 mm spark plug wrench, remove the
spark plug.
(4) Disconnect the 4 fuel injector connectors.
(5) Install the spark plug into the ignition coil, and
then connect the ignition coil connectors.
(6) Ground the spark plug.
(7) Check that sparks occur at the spark plug while
the engine is being cranked.
NOTICE:
• Be sure to ground the spark plugs when
checking them.
• If the ignition coil has been struck or
dropped, replace it.
• Do not crank the engine for more than 2
seconds.
If sparks do not occur, Perform the spark test.
(8) Using a 16 mm plug wrench, install the spark
plug.
