Ignition Coil 1.6L & 1.8L & 2.0L
Description
The ignition coil consists of primary and secondary groups of wire. The primary wire is located on one end of the coil.
One end of the wire is connected to power and the other end is connected to the Engine Control Module (ECM). The
secondary coil connects two spark plugs. They form a loop and provide high-voltage output.
Operation
When the primary wire is connected to power, current will flow causing a strong magnetic field to form. When the
primary wire is disconnected, the magnetic field will collapse into the secondary wire causing very high voltage out-
put.
Removal & Installation
1. Remove the engine cover.
2. Disconnect the negative battery cable.
3. Disconnect the ignition coil electrical connector.
4. Twist the spark plug wires (1) from the ignition coiland remove the four spark plug wires.

The fuel delivery system is enabled when it reaches the following conditions:
•Turn the ignition switch ON (engine off), the fuel delivery system is enabled for 3-6 seconds.
• The Engine Control Module (ECM) receives a Crankshaft Position (CKP) sensor signal.
The fuel injectors are a solenoid-operated valve that meter fuel flow to each cylinder. The fuel injectors are opened
and closed constantly during engine operation. The amount of fuel is controlled by the length of time the fuel injector
is held open. The fuel injectors are powered by a 12 V source and are controlled through the ground side of the
circuit by the ECM.
The fuel pump operation is defined in the fuel system control strategy and is controlled by the ECM.

Fuel Pressure Relief Procedure
Description
WARNING!
Fuel in the fuel system remains under high pressure, even when the engine is not running. Before servicing or
disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved to
prevent accidental spraying of fuel. Failure to follow these instructions may result in serious personal injury or
death.
Perform the following procedure to relieve fuel pressure from the fuel system:1. Remove the cover of the front fuse and relay box.
2. Identify and remove the fuel pump relay from the front fuse and relay box.
3. Start and run engine until it stalls.
4. Attempt to restart engine until it will no longer run.
5. Turn the ignition key to the OFF position.
Fuel Pump
Description
The fuel pump assembly contains the fuel pump motor and fuel level sensor.
Operation
The Engine Control Module (ECM) activates the fuel pump relay for several seconds after the ignition switch is
turned ON. When the relay is activated, it provides voltage to the fuel pump. When the ECM receives an engine
speed signal from the Crankshaft Position (CKP) sensor and a signal from the Immobilizer control module, the ECM
will energize the fuel pump relay.
NOTE :
• The electric fuel pump has different flow ratings based on engine requirements
• For service, the part number of the replacement fuel pump must be the equivalent of the original fuel pump
• Do not operate the fuel pump dry, this will damage the fuel pump
• Keep the fuel tank and pipeline clean, and replace the fuel filter if the fuel pump is replaced
Removal & Installation
WARNING!
Release fuel system pressure before servicing fuel system components. Service vehicles in well-ventilated areas
and avoid ignition sources. Never smoke while servicing the vehicle. This may result in personal injury or death.
NOTE :
The following special tool is required to perform the repair procedure:
•CH-20032 - Fuel Pump Remover
1. Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).
2. Disconnect the negative battery cable.
3. Remove the rear seat cushion.

5. Disconnect the fuel pump connector (3) and thefuel delivery hose (2) and fuel return hose (1).
6. Using special tool CH-20032, remove the fuel pump mounting cover (4).
7. Pull the fuel pump up and out of the fuel tank.
WARNING!
Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-
related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these
instructions may result in serious personal injury or death.
Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when
working on or near any fuel-related component. Highly flammable mixtures are always present and may be
ignited. Failure to follow these instructions may result in serious personal injury or death.
When handling fuel, always observe fuel handling precautions and be prepared in the event of fuel spillage.
Spilled fuel may be ignited by hot vehicle components or other ignition sources. Failure to follow these instruc-
tions may result in serious personal injury or death.
NOTE :
Make sure not to spill fuel inside of the vehicle. 8. Tip the fuel pump on its side and drain the fuel from the fuel pump and remove the fuel pump from the vehicle. NOTE: To keep the fuel tank portion clean and to avoid damage and foreign materials, cover them completely
with plastic bags or something similar.
9. Remove and discard the seal from the fuel tank.
10. Installation is in the reverse order of removal.
Installation Notes:
• Install a new seal to the fuel pump sealing surface.
• Turn the ignition switch to ON (without starting the engine) to apply fuel pressure to the fuel system, then
check the connections for fuel leaks.
• Start the engine and let it idle and check for fuel leaks at the fuel system connections.
