What is an Electric Fuel Pump? (with pictures) The electric fuel pump is an alternative to a manual fuel pump system and is widely considered to be a better use of technology with regards to the function and operation of motor vehicles. An electric fuel pump is small and thermally insulated to prevent sparking. Generally, it consists of a 12 volt electric motor attached to a pump assembly that pulls fuel in as the motor spins, and pushes it out through a different line that goes to the engine compartment. Fuel Pump Relay Function And Testing Procedures A fuel pump relay functions primarily to maintain a consistent voltage supply to the fuel pump. The ignition or powertrain control module (PCM) usually controls the fuel pump relay. When switched on the fuel pump relay will provide current to the fuel pump so that it may function.

Instead of being constantly powered at 100% duty cycle, PWM fuel pumps have a varying fuel pressure due to controlled electrical operation. With the ignition key on, full system voltage is supplied to the fuel pump. ... determines the desired fuel pressure at the engine and pulses the negative side of the fuel pump circuit to provide the ... Fuel pump Though electrical components (such as a fuel pump) can spark and ignite fuel vapors, liquid fuel will not explode (see flammability limit) and therefore submerging the pump in the tank is one of the safest places to put it. In most cars, the fuel pump delivers a constant flow of gasoline to the engine; fuel not used is returned to the tank. FUEL PUMP ELECTRICAL CIRCUIT DIAGNOSIS > CIRCUIT DESCRIPTION FUEL PUMP ELECTRICAL CIRCUIT DIAGNOSIS > CIRCUIT DESCRIPTION Tip: 06 H3 intermittent no start The control module enables the fuel pump relay when the ignition switch is turned ON. The control module will disable the fuel pump relay within 2 seconds unless the control module detects ignition reference pulses. The control module Fuel Injection circuit description Speedy Jim CR1 contact powers the electric fuel pump and the Aux Air Regulator. When the engine begins to run on its own, the pump switch in the air flow sensor (air box) closes 39 to 36. This contact closure provides a "holding" circuit to relay CR1. Because of the holding circuit, power can now be removed from terminal 86 as the starter is de energized. CIRCUIT TEST J FUEL PUMP CIRCUIT (RELAY & INERTIA SWITCH) When ignition switch is in the ON or START position, the PCM connects FUEL PUMP circuit (PCM terminal No. 22) to ground. The fuel pump relay is energized and electrical current flows to the fuel pump. If PCM does not receive ignition PIP signal within 2 seconds, FUEL PUMP circuit is opened and fuel pump operation is terminated. Toyota Camry 2002 2006: Fuel Diagnostic Guide Camryforums Toyota Camry 2002 2006: Fuel Diagnostic Guide. The fuel system is tasked with supplying fuel from the gas tank to the combustion chamber.
