Fuel System — Description The fuel system consists of a fuel tank, a high pressure fuel pump built into the tank, a PGM-FI main relay, a fuel filter, a fuel pressure regulator, fuel injectors, and fuel supply and return lines. This system...
Relieve pressure in the fuel system Before disconnecting fuel lines or hoses, relieve system pressure by loosening the 12mm type «banjo» on top of the fuel filter. Warning! Do not smoke while working on the fuel system. Do not create sparks or open flames...
Checking the pressure in the fuel system 1. Relieve pressure ( see above ). 2. Loosen the 12mm bolt type «banjo» on the fuel filter while holding the filter with another wrench. Screw on the 12mm adapter and attach the special tool. 1. FUEL PRESSURE GAUGE...
Fuel injectors — test 1. Disconnect the connector from the fuel injector and measure the resistance between the 2 fuel injector terminals. There should be a resistance of 12-15 ohms. If the resistance is not as specified, replace the fuel...
Fuel pressure control Description The regulator maintains a constant pressure of the fuel supplied to the injectors. When the difference between the fuel pressure and the pressure in the manifold exceeds 290 kPa, the diaphragm is pressed...
Fuel filter — replacement Warning! Do not smoke while working on the fuel system. Do not create sparks or open flames in the workplace. When replacing the fuel filter, keep a safe distance between the battery terminals and the tool. The fuel...
Fuel pump — test Warning! Do not smoke while working on the fuel system. Do not create sparks or open flames in the workplace. If you suspect that the fuel pump is out of order, check if it works; when the ignition key is turned to the...
