Fuel Pressure Inspection
Be sure the battery is fully charged.

Be sure to place a piece of cloth around the fuel supply
pipes of the fuel pump and the throttle body assy.
Fuel is flammable and explosive under certain con-
ditions and can cause severe burns. Be prepared
for fuel spillage; any spilled fuel must be completely
wiped up immediately. When the fuel hose is dis-
connected, fuel spills out from the hose and the
pipe because of residual pressure. Cover the hose
connection with a piece of clean cloth to prevent

Fuel is extremely flammable and can be explosive
under certain conditions resulting in serious injury
or death. Do not try to start the engine with the fuel
Connect the fuel pump lead connector.
Turn the engine stop switch to run position.
Turn the ignition switch to ON. The fuel pump will turn 3
seconds, and then stop.
Turn the ignition switch to ON and inspect the fuel line
leakage after installing the special tools.
Do not drive the fuel pump 3 seconds or more with-
out the fuel in the fuel tank. If the fuel pump is driven
without the fuel, it may be damaged.
Start the engine, and let it idle.
Measure the fuel pressure with the engine idling.
