Why is fuel not getting to the engine?
If a lack of fuel has been determined to be the cause of a non-starting engine, then next it must be determined if that lack of fuel is caused by an electrical problem, the fuel pump, a plugged fuel filter, a faulty fuel regulator, or the fuel injectors.
What controls the amount of fuel that the carburetor or fuel injectors supply to the engine?
The amount of fuel supplied to the engine is determined by the amount of time the fuel injector stays open. This is called the pulse width, and it is controlled by the ECU. The injectors are mounted in the intake manifold so that they spray fuel directly at the intake valves.
What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
Can a bad fuel filter cause an engine to wear out?
While it’s entirely possible that your fuel pump is just old, it’s also possible that a clogged fuel filter is causing the pump to wear out prematurely. If your engine sounds like it’s hacking out a lung, then it’s possible your fuel system is compromised on account of a bad fuel filter.
How does fuel get out of the injection pump?
The fuel is dispersed from the injection pump to the combustion chamber via a fairly simple process. Pressurized fuel enters the fuel injector. Based on a signal from an electrically controlled solenoid valve – the solenoid valve acts as a type of on / off valve – the fuel enters a plunger, which prepares the fuel for the final exit.
Why does the fuel pump stop working on my car?
WHY DOES THE FUEL PUMP STOP WORKING? The main reason, in most cases, is material fatigue. You see, the fuel pump is essentially a direct current electric motor that has an impeller inside it. Once it gets power input, it momentarily starts to pump gas and provide a stable and high fuel pressure to the engine.
