INSPECTION BEFORE REMOVAL
1. Disconnect vacuum hose, and connect a vacuum gauge via 3-way connector.

Disconnect point where vacuum from vacuum pump can be measured directly and install 3-way con-
nector.
2. Start engine and measure generated vacuum at idle speed.

If out of standard, check for air suction in vacuum route, and measure again.

If still outside of standard, replace vacuum pump.

CAUTION:

Before removing and installing fuel pump, be sure to remove sprocket. Do not loosen or remove
installation nut in the center of fuel pump. If loosened or removed, replace fuel pump.

After removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.
