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.

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.

Cylinder Head Inspection for
Warpage
Remove the cylinder head {see page 6-23).
Inspect the camshaft (see page 6-29).
Check the cylinder head for warpage. Measure
along the edges, and three ways across the center.
. lf warpage is less than 0.05 mm (0.002 in.)
cylinder head resurfacing is not required.. lf warpage is between 0.05 mm (0.002 in.) and
0.2 mm (0.008 in.), resurface the cylinder head.. Maximum resurface limit is 0.2 mm (0.008 in,)
based on a height of 104 mm (4.09 in.).
