Description
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned ON to improve engine start ability. If the ECM receives a engine speed signal from the camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.
Component Function Check
1.CHECK FUEL PUMP FUNCTION
: Vehicle front (Illustration shows the view with intake air duct removed)
Fuel pressure pulsation should be felt on the fuel feed hose for 1 second after ignition switch is turned ON.
Diagnosis Procedure
