YES-Repair short to ground in the wire between
the alternator and the ECM.I
NO-Check that the terminals are firmly seated at
the ECM connector B. lf OK, substitute a known-
good ECM, and recheck (see page 11-6).
lf prescribed voltage is now available. replace the
original ECM,I
Turn the headlights and ignition switch OFF.

Install the air cleaner housing cover (A) and
connect the intake air temperature (lAT) sensor
connector (B),
42. Installthe breather hose (C) and vacuum hose 1D).

Installthe battery. Clean the battery posts and
cable terminals with sandpaper, then assemble
them and apply grease to prevent corrosion.
Check that the transmission shifts into gear
smoothly.
Inspect for fuel leaks. Turn the ignition switch ON(ll) {do not operate the starter) so that the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat this operation two or three times, then
check for fuel leakage at any point in the fuel line.
Refillthe engine with engine oil (see page 8-5).
Refill the transmission with fluid (see page 13-3).
Refill the radiator with engine coolant, and bleed
air from the cooling system with the heater valve
open (see page 10-6).
Perform the engine control module (ECM) idle learnprocedure (see page 11-139).
Inspect the idle speed (see page 1 1-138).
Inspect the ignition timing (see page 4-17).
Check the wheel alignment {see page 18-4).
Enter the anti-theft code for the radio, then enter
the customer's radio station presets.
Set the clock.

Engine Compression Inspection
1. Warm up the engine to normal operating
temperature (cooling fan comes on).
2. Turn the ignition switch OFF.
3. Remove the intake manifold cover (see step 1 onpage 6-22).
4, Disconnect all four injector connectors.
5. Start the engine, and let it run until it stalls.
6. Remove the iour ignition coils (see page 4-18).
7. Remove the four spark plugs.
8. Attach the compression gauge to the spark plug

Open the throttle fully, then crank the engine with
the starter motor and measure the compression.
Compression Pressure
Above 930 kpa (9.5 kgf/cm', 135 psi)
Measure the compression on the remaining
cylinders,
Maximum vadation
Within 200 kPa (2.0 kgf/cm', 28 psi)
lf the compression is not within specifications,
check these items, then remeasure the
compressron.

to prevent corrosion.
22. After installation, checkthatall tubes, hosesand
connectors are installed correctly.
23. Inspectforfuel leaks. Turn the ignition switch ON
{ll) {do not operate the starter) so that the fuel pump
runs for about 2 seconds and pressurizes the fuel
line. Repeat thls operation two or three times, then
check for fuel leakage at any point in the fuel line.
24. Refillthe radiator with engine coolant, and bleed
air from the cooling system with the heater valve

Gylinder Head Cover lnstallation
1. Thoroughly clean the head cover gasket and the
groove.
2. Installthe head cover gasket (A) in the groove of
the cylinder head cover (B).
Check that the mating surfaces are clean and dry.
Apply liquid gasket. P/N 08718-0009, on the chain
case and the No.5 rocker shaft holder mating areas.
NOTE: Do not install the parts if 5 minutes or more
have elapsed since applying liquid gasket. Instead,
reapply liquid gasket after removing old residue.
