PRECAUTION ON FUEL SYSTEM SERVICE
Work must be done with no smoking, in a well-ventilated area and
away from any open flames.
As fuel feed line (between fuel pump and fuel delivery pipe) is still
under high fuel pressure even after engine was stopped, loosen-
ing or disconnecting fuel feed line directly may cause dangerous
spout of fuel to occur where loosened or disconnected.
Before loosening or disconnecting fuel feed line, make sure to re-
lease fuel pressure according to “FUEL PRESSURE RELIEF
PROCEDURE”. A small amount of fuel may be released after the
fuel line is disconnected. In order to reduce the chance of person-
al injury, cover the fitting to be disconnected with a shop cloth. Put
that cloth in an approved container when disconnection is com-
pleted.
Never run engine with fuel pump relay disconnected when engine
and exhaust system are hot.
Fuel or fuel vapor hose connection varies with each type of pipe.
When reconnecting fuel or fuel vapor hose, be sure to connect
and clamp each hose correctly referring to left figure Hose Con-
nection.
After connecting, make sure that it has no twist or kink.
When installing injector or fuel delivery pipe, lubricate its O-ring
with spindle oil or gasoline.
When connecting fuel pipe flare nut, first tighten flare nut by hand
and then tighten it to specified torque.

“IG COIL METER”Main relay
Ignition switch
In fuseMalfunction indicator lamp in combination meter
TABLE A-1 MALFUNCTION INDICATOR LAMP CIRCUIT CHECK – LAMP DOES
NOT COME “ON” AT IGNITION SWITCH ON (BUT ENGINE AT STOP)
CIRCUIT DESCRIPTION
When the ignition switch is turned ON, ECM (PCM) causes the main relay to turn ON (close the contact point).
Then, ECM (PCM) being supplied with the main power, turns ON the malfunction indicator lamp (MIL). When the
engine starts to run and no malfunction is detected in the system, MIL goes OFF but if a malfunction was or is de-
tected, MIL remains ON even when the engine is running.
INSPECTION
STEPACTIONYESNO
1MIL Power Supply Check
1) Turn ignition switch ON.
Do other indicator / warning lights in
combination meter comes ON?Go to Step 2.“IG COIL METER” fuse blown,
main fuse blown, ignition
switch malfunction, “B/W”
circuit between “IG COIL
METER” fuse and
combination meter or poor
coupler connection at
combination meter.
2ECM (PCM) Power and Ground Circuit
Check
Does engine start?Go to Step 3.Go to TABLE A-3 ECM (PCM)
POWER AND GROUND
CIRCUIT CHECK.
If engine is not cranked, go to
DIAGNOSIS in SECTION 8A.
3MIL Circuit Check
1) Turn ignition switch OFF and disconnect
connectors from ECM (PCM).
2) Check for proper connection to ECM
(PCM) at terminal C02-17.
3) If OK, then using service wire, ground
terminal C02-17 in connector
disconnected.
Does MIL turn on at ignition switch ON?Substitute a known-
good ECM (PCM) and
recheck.Bulb burned out or “V/Y” wire
circuit open.
