Fuel Pump Electrical Circuits Description and Operation Print ... Fuel pump electrical circuit diagnosis (no fuel pressure testing) GM : end faq. How a fuel pump works | How a Car Works Electric fuel pump An electric pump has a similar diaphragm mechanism; it is worked by a rod that is drawn into a solenoid switch until it opens a set of contacts to turn off the current. An electric pump has a similar diaphragm and valve arrangement, but instead of the camshaft, a solenoid (an electromagnetic switch ) provides the pull on the diaphragm. Fuel Pump Electrical Circuit Diagnosis Powertrain Fuel Pump Electrical Circuit Diagnosis System Description The engine control module (ECM) enables the fuel pump relay when the ignition switch is turned ON. The ECM will disable the fuel pump relay within 30 seconds unless the control module detects ignition reference pulses.

Recorded during my Engine Performance class at Rosedale Technical College. I have many more videos just like this available only on ScannerDanner Premium. 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 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.

Fuel pump The fuel sending unit assembly may be a combination of the electric fuel pump, the filter, the strainer, and the electronic device used to measure the amount of fuel in the tank via a float attached to a sensor which sends data to the dash mounted fuel gauge. The fuel pump by itself is a relatively inexpensive part. Toyota Camry 2002 2006: Fuel Diagnostic Guide Inside the fuel tank is the fuel pump and fuel pressure regulator. When the ignition is turned to the "on" position, the pump energizes and supplies fuel pressure to the injectors. Once the engine reaches a certain point in its rotation, the computer commands the injector to open. Fuel Pump Diagnostics Using Voltage Drops and Current Draw A resistor or insulator prevents the flow of electricity in a circuit. Resistance can be caused by corrosion, fretting and even air. If you were to put a 1.0 ohm resistor in a fuel pump circuit, it would lower the 13.25 volts prior to 9.78 volts. This is a voltage drop of almost 4.0 volts. Pulse Width Modulated Fuel Pumps technician.academy Simply put, a pump is on when it receives electrical power and it’s off when there is no power. When it’s on, it’s also known as 100% duty cycle. Pulse width modulation is vastly different. Instead of being constantly powered at 100% duty cycle, PWM fuel pumps have a varying fuel pressure due to controlled electrical operation.
