Engine Electrical System

Starting system

When the ignition key is turned to the start position,
current flows and energizes the starter motor's solenoid
coil.
The solenoid plunger and clutch shift lever are
activated, and the clutch pinion engages the ring gear.
The contacts close and the starter motor cranks. In
order to prevent damage caused by excessive rotation
of the starter armature when the engine starts, the
clutch pinion gear overruns.
Troubleshooting
1. Remove the fuel pump relay(A) from the fuse box.
2. With the shift lever in N or P (A/T) or clutch pedal
pressed (M/T), turn the ignition switch to "START"
If the starter normally cranks the engine, starting
system is OK. If the starter will not crank the engine
at all, go to next step.
If it won't disengage from the ring gear when you
release key, check for the following until you find the
cause.
• Solenoid plunger and switch malfunction.
• Dirty pinion gear or damaged overrunning clutch.
3. Check the battery condition. Check electrical
connections at the battery, battery negative cable
connected to the body, engine ground cables, and
the starter for looseness and corrosion. Then try
77
starting the engine again.
If the starter cranks normally the engine, repairing the
loose connection repaired the problem. The starting
system is now OK.
If the starter still does not crank the engine, go to
next step.
Disconnect the connector from the S-terminal of
solenoid. Connect a jumper wire from the B-terminal of
solenoid to the S-terminal of solenoid.
If the starter cranks the engine, go to next step.
If the starter still does not crank the engine, remove
the starter, and repair or replace as necessary.
4. Check the following items in the order listed until you
find the open circuit.
• Check the wire and connectors between the
driver's under-dash fuse/relay box and the ignition
switch, and between the driver's under-dash
fuse/relay box and the starter.
• Check the ignition switch (Refer to BE group -
ignition system)
• Check the transaxle range switch connector or
ignition lock switch connector.
• Inspect the starter relay.
