Why do you need to bleed the injection component system?

Bleeding the low pressure side prevents, among other things, defects to the high pressure pump which can occur during filter change without manual bleeding, for example.

How do I get my diesel to start after I run out of fuel?

Prime the fuel system by turning the ignition on (Run position) for 30 seconds, but do not start the engine. This allows the pump to prime the system. Turn the ignition off, and then crank it for 15 seconds. If it does not start, repeat the first task and this one until it starts (cycle the key).

How does a rotary fuel injection pump work?

How do you bleed a Stanadyne injection pump?

Can fuel injectors bleed?

Most are equipped with bleed screws, and thus the procedure is the same. Then you must bleed the high-pressure fuel system, which is done by loosening the union nuts between the top of the fuel injectors and the fuel line; it just takes a turn or two. Once loosened, use the starter to crank the engine for 10 seconds.
