Check for Wear and Damage

The starter should crank the engine smoothly and steadily.

If the starter engages, but cranks the engine erratically,

remove it, and inspect the starter drive gear and torque

converter ring gear for damage.

• Check the drive gear overrunning clutch for binding

or slipping when the armature is rotated with the

drive gear held. If the clutch is damaged, replace the

clutch assembly.

Check Cranking Voltage and Current Draw

Cranking voltage should be no less than 8.0 volts.

Current draw should be no more than 450 amperes.

If cranking voltage is too low, or current draw too high,

check for:

Dead or low battery

Open circuit in starter armature commutator segments

Starter armature dragging

Shorted armature winding

Excessive drag in engine

Check Cranking rpm

Engine speed during cranking should be above 100 rpm.

If speed is too low, check for:

Loose battery or starter terminals

Excessively worn starter brushes

Open circuit in commutator segments

Dirty or damaged helical spline or drive gear

Defective drive gear overrunning clutch

Check Starter Disengagement

With the shift lever in or , turn the ignition switch to

"START (III)", and release to "ON (II)". The starter drive

gear should disengage from the flywheel ring gear when

you release the key.

If the drive gear hangs upon the flywheel ring gear, check

for:

• Solenoid plunger and switch malfunction

• Dirty drive gear assembly or damaged overrunning

PGM-FI System

The PGM-FI system on this model is a sequential multiport fuel injection system.

Fuel injector Timing and Duration

The ECM contains memories for the basic discharge durations at various engine speeds and manifold air flow rates. The

basic discharge duration, after being read out from the memory, is further modified by signals sent from various sensors

to obtain the final discharge duration.

Idle Air Control

Idle Air Control Valve (IAC Valve)

When the engine is cold, the A/C compressor is on, the transmission is in gear, the brake pedal is depressed, the P/S load

is high, or the alternator is charging, the ECM controls current to the IAC Valve to maintain the correct idle speed.

Ignition Timing Control

• The ECM contains memories for basic ignition timing at various engine speeds and manifold air flow rates. Ignition

timing is also adjusted for engine coolant temperature.

• A knock control system is also used. When detonation is detected by a knock sensor (KS), the ignition timing is retarded.

Other Control Functions

1. Starting Control

When the engine is started, the ECM provides a rich mixture by increasing fuel injector duration.

2. Fuel Pump Control

• When the ignition switch is initially turned on, the ECM supplies ground to the PGM-FI main relay that supplies

current to the fuel pump for two seconds to pressurize the fuel system.

• When the engine is running, the ECM supplies ground to the PGM-FI main relay that supplies current to the fuel pump.

• When the engine is not running and the ignition is on, the ECM cuts ground to the PGM-FI main relay which cuts

current to the fuel pump.

3. Fuel Cut-off Control

• During deceleration with the throttle valve closed, current to the fuel injectors is cut off to improve fuel economy at

speeds over 1,250 rpm.

• Fuel cut-off action also takes place when engine speed exceeds 7,100 rpm, regardless of the position of the throttle

valve, to protect the engine from over-revving.
