Over time, residue can build up in the fuel system, and enough gunk, grime and grease can clog up the entire fuel injector pump.

What happens if the fuel injector can’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.
