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.

How much psi does a fuel injector pump use?

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.

How does the injector pump on a diesel engine work?

The injector pump on a diesel engine pushes the fuel to the engine and makes sure it’s at the proper pressure. If this pump fails, the engine won’t get the fuel it needs to run. To fix the problem, the diesel injector pump must be taken off of the vehicle and replaced with a new one.
