How To Start A Car With A Bad Fuel Pump
Car engines are intriguing machines assembled with several systems built to deliver optimal performance. Engines require a constant fuel supply, and the fuel pump is the system used to provide it.
Mechanical fuel pumps move fuel from the fuel tank to the engine under low pressure through the carburetor. The fuel mixes with air inside the carburetor, the liquid is then pumped into the engine. Mechanical fuel pumps are outside of the fuel tank. The camshaft operates a switch on the fuel pump that uses a diaphragm situated inside the carburetor. The control switch can pull the diaphragm down, allowing the fuel to rush into the carburetor, or pull the diaphragm up, causing pressure to push the fuel out.
Electric fuel pumps send a positive electrical current through the fuel lines causing enough force to send fuel to the engine. The electrical current needed is regulated from an electrical ignition switch. The fuel in this system does not mix with air until it hits the cylinder.
The fuel moving from the tank to the engine completes several functions that manage the car’s power. One of the steps is the pump causing the correct air to fuel mixture that produces the energy to start your vehicle. There is always a concern about engine damage if a car part fails, but the car will not start if the fuel pump quits.
