Installation
Reverse removal procedure for installation noting the
following.
• Replace injector O-ring (1) with new one using care not to damage it.
• Check if cushion (2) is scor ed or damaged. If it is,
replace with new one.
• Apply thin coat of fuel to O-rings (1) and then install injectors (3) into delivery pipe (4) and cylinder head.
Make sure that injectors rota te smoothly (6). If not,

WARNING!
Before starting the following procedure, be
sure to observe “Precautions on Fuel System
Service” in order to reduce the risk or fire
and personal injury.

NOTE
The fuel pressure regulator is incorporated
with the fuel pump assembly so individual
inspection of it is impossible.

1) Remove filler cap and turn ON ignition switch (2).
Then fuel pump operating sound should be heard
from fuel filler (1) for about 2 seconds and stop. Be
sure to reinstall fuel filler cap after checking.
If the check result is not satisfactory, go to “Fuel
Pump and Its Circuit Check in Section 1A”. 2) Turn OFF ignition switch and leave over 10 minutes
as it is.
3) Fuel pressure should be felt at fuel feed hose (1) for about 2 seconds after ignition switch ON.
If fuel pressure is not felt, go to “Fuel Pressure
Check in Section 1A”.

Ignition System
General Description
Ignition System ConstructionS7RS0B1801001
The ignition system is an electronic (distributorless) ignition system. It consists of the parts as described below.
• ECM
It detects the engine and vehicle conditions through the si gnals from the sensors, determines the most suitable
ignition timing and time for electricity to flow to the primar y coil and sends a signal to the ignitor (power unit) in the
ignition coil assembly.
• Ignition coil assembly (including an ignitor)
The ignition coil assembly has a built -in ignitor which turns ON and OFF the current flow to the primary coil
according to the signal from ECM. When the current flow to the primary coil is turned OFF, a high voltage is induced
in the secondary coil.
• High-tension cords and spark plugs
• CMP sensor (Camshaft position sensor) and CKP sensor (Crankshaft position sensor)
Using signals from these sensors, ECM identifies the specific cylinder whose piston is in the compression stroke,
detects the crank angle and adjusts in itial ignition timing automatically.
• TP sensor, ECT sensor, MAP sensor, MAF sensor, IAT sensor, knock sensor and other sensors / switches
Although this ignition system does not have a distributor, it has two ignition coil assemblies (one is for No.1 and No.4
spark plugs and the other is for No.2 and No.3 spark plugs). W hen an ignition signal is sent from ECM to the ignitor in
the ignition coil assembly for No.1 and No.4 spark plugs, a high voltage is induced in the secondary coil and that
passes through the high-tension cords and causes No.1 and No.4 spark plugs to spark simultaneously. Likewise,
when an ignition signal is sent to the ignitor in the ot her ignition coil assembly, No.2 and No.3 spark plugs spark
simultaneously.
