What does fuel pump fault mean?
Car Will Not Start If the fuel pump fails completely — to the point of not being able to provide enough fuel for the engine to run, the vehicle will refuse to start. The engine will still crank when the key is turned, but it will be unable to start due to the lack of fuel.
Why are my fuel pump injectors not working?
In 2006, diesel fuel production was tweaked to compensate for ultra low sulfur diesel fuel (ULSD), and diesel engine owners have noticed more “dirty fuel” difficulties than before. If your main goal in life was to destroy diesel fuel pump injectors, you’d run your car with the fuel tank as close to empty as possible.
What causes a diesel fuel pump to back up?
A clean diesel fuel pump injector is a happy diesel fuel pump injector. Over time, residue can build up in the fuel system, and enough gunk, grime and grease can clog up the entire fuel injector pump. The spray tip (where the fuel leaves the injector and enters the combustion chamber) is particularly prone to “backing up,” so to speak.
Why does my Generator keep failing to start?
Closer tolerances within the fuel systems to meet today’s emission requirements make fuel systems more susceptible to air affecting startup. This is not as common with older generators — many of which may have a leak in a line or check valves that are not properly holding the fuel in the engine.
What causes the fuel pump bearings to wear out?
With a near-empty tank, the fuel system is suddenly pushing air instead of diesel fuel. Anything but diesel fuel can wear out the fuel pump bearings, which means the fuel injectors will not receive the fuel at the pressurized level (30,000 psi, 40,000 psi, etc.) it should be.

What causes a diesel generator to not start?
Diesel engine generators are designed to operate with a load — most effectively in the 70% to 80% range of rated output. When generators operate considerably below the rated output level, the engine can start to over-fuel or “wet stack” and damage the engine. “Not in auto” messages are the direct result of human error.

What causes an oil leak in a generator?
Most often, oil leaks are not in fact leaks but the result of “wet stacking” (or “engine slobber”) caused by excessive no-load run time. Diesel engine generators are designed to operate with a load — most effectively in the 70% to 80% range of rated output.
