3.
Measure the spark plug gap. Make sure the gap is
correct.
4.
Replace the spark plug.
5.
Replace the spark plug cap.
6.
Reconnect the high tension lead, the ignition coil and
the spark plug cap. Make sure the screw engages
the center wires in high tension lead.
7.
Check all connections. With the engine running, wig-
gle each connection. If the engine stops running or
runs poorly, check for wire damage.
8.
Replace the wiring harness.
9.
Replace the ignition coil.
10. Measure the resistance between the IGN module
mounting bolt and the high tension lead at the spark
plug connection in the cap. Reading should be
13.7~14.7 k
ȍ
.
Fuel Pump
1.
Turn the key to the ON position. Within 10 seconds,
measure the voltage between terminal #1 at the fuel
pump connection and the battery ground. Verify input
voltage to pump is 9.0 to 15.0 VDC.
2.
Verify at least 1.0 amp of current is available. Use
jumper wire (with in-line 5 amp fuse) to connect the
fuel pump to the battery positive terminal.
3.
Verify that there is sufficient fuel in the fuel tank.
4.
Verify that the fuel filter is not contaminated with
debris.
5.
Swap the fuel filter/hose with a new filter and rubber
hose.
6.
Verify the outlet hose is not pinched, kinked or leak-
ing.
7.
Verify that the fuel tank vent is operational.
8.
Verify that fuel pressure is 2.75 to 3.75 Bar
(39.9~54.4 psi).
9.
Change the entire PFA.
Other
1.
Turn the key to the ON position. Within 10 seconds,
measure the voltage between the terminal at the
ECR relay connection and the battery ground. Volt-
age should measure same as battery voltage.
2.
Replace the TBA (with ECM).
3.
Tighten screws.
4.
Replace the injector.
5.
Verify the injector resistance is 12.0±0.6
ȍ
.
6.
Verify that the injector O-ring is not damaged.
7.
Replace the engine temperature sensor.
8.
Replace the air cleaner.
9.
Replace fuel.
10. Clean out or replace the fuel line.
11. Turn the key to the ON position. Within 10 seconds,
measure the voltage between the terminals at Fuse
#1, then terminals at the Fuse #2 connection and
battery ground. Voltage should measure the same as
the battery voltage.
