Fuel Pump Electrical Circuit
Fuel Pump Electrical Circuit
When the key is first turned "ON," the PCM energizes the fuel pump relay for two seconds to build up the fuel pressure quickly. If the engine is not
started within two seconds, the PCM shuts the fuel pump off and waits until the engine is cranked. When the engine is cranked and the 58X crankshaft
position signal has been detected by the PCM, the PCM supplies 12 volts to the fuel pump relay to energize the electric in-tank fuel pump.
An inoperative fuel pump will cause a "no-start" condition. A fuel pump which does not provide enough pressure will result in poor performance.
Fuel Pump Relay
In order to control the FPS operation, the FPS relay is provided. When the starter switch is turned to "ON" position, the FPS relay operates the FPS for
2 seconds.
When the key turned to "START" position, the Engine Control Module receives the reference pulse from the Ignition Control Module and it operates the
relay, again causing the FPS to feed fuel.
Fuel Rail
Fuel Rail
The fuel rail is mounted to the top of the engine and distributes fuel to the individual injectors. Fuel is delivered to the fuel inlet tube of the fuel rail by
the fuel lines. The fuel goes through the fuel rail to the fuel pressure regulator. The fuel pressure regulator maintains a constant fuel pressure at the
injectors. Remaining fuel is then returned to the fuel tank.
