NOTE

Be sure the battery is fully charged.

Be sure to place a piece of cloth around the fuel outlet pipe of the fuel pump and the delivery pipe of the throttle body assy.

WARNING

Fuel is flammable and explosive under certain conditions and can cause severe burns. Be prepared for fuel spillage; any spilled fuel must be completely wiped up immediately. When the fuel hose is disconnected, 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 spillage.

Fuel Pressure Inspection


WARNING

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 hoses disconnected.

The fuel pump should operate for 3 seconds, and then should stop.

NOTE

After turning on the engine stop switch and ignition switch, inspect the fuel leakage from the connected portion of the special tools.

NOTICE

Do not drive the fuel pump 3 seconds or more without the fuel in the fuel tank. If the fuel pump is driven without the fuel, it may be damaged.

Fuel Pressure (with Engine Idling) Standard: 294 kPa (3.0 kgf/cm², 43 psi)

NOTE

The gauge needle will fluctuate. Read the pressure at the average of the maximum and minimum indications.

Turn the ignition switch to OFF.

After above checks, measure the fuel pressure again.

Remove the fuel pressure gauge, hoses and adapter.

Install the removed parts (see appropriate chapters).

Start the engine and check for fuel leakage.
