Quick Details

The detection of fuel pressure system. King Prince's cab to check the fuel gauge and the fuel gauge, connecting the oil pipe and the oil gauge. Start the engine and make it run at idle speed, and the fuel meter reading should be in the range of 270~320kpa. If the pressure exceeds the technical specifications, you need to replace the fuel pressure regulator and fuel filter. Check the jet nozzle. The engine into the idle, respectively disconnect each injection nozzle plug, check the idle if there are changes, the nozzle if the disconnection of each cylinder, reduce the idle speed is basically the same, the nozzle to work properly. When disconnected from a nozzle, no change in the engine idle speed and stability, need measuring nozzle plug resistance value is 10~13, if you do not meet the criteria to replace fuel injector. Of course, also need to carry out the PGM-FI main relay and plug connection point between the wire inspection, plug connection point and the injection nozzle between the wire is broken, poor connection, such as the prince of gold. Fuel pump and fuel pump circuit check. Fuel pump check: unscrew the fuel tank cap, the ignition switch in the ON position, the fuel filler can hear the pump running sound, in the normal condition, when the ignition switch is in the ON, the fuel pump should be run for 2 seconds. If the pump is not running, first check whether the burn pump insurance. Check whether the PGM-FI main relay and the plug terminals are conductive and so on. King Prince cab next also check the pressure of the cylinder, the gap between the intake and exhaust valves, fuel vapor control solenoid valve, EGR valve cylinder.
