Default simple diesel engine question

I haven't seen anyone send the following suggestions, so ...

To get it running after a long layoff, spray WD-40 in the air intake. It
will run on that stuff while the fuel pumps fill the lines and you bleed the
air from the system (crack the connection at the injector).

The two levers are (most likely) the "throttle" and the cut-off. The
cut-off will be either on or off. The throttle, which actually controls the
amount of fuel metered to each injector, is a continuous control from idle
to full power.

Be good to the injection pump/metering system. It costs more than the whole
rest of the motor. Clean fuel, clean filters, don't take it apart.

A friend bought a boat that had a diesel set in the boat, but not
hooked up. The motor was very stiff so I pulled the injectors, put in
penetrating oil, turned her by hand the next day, then on the starter
and she loosened up alot; but little fuel came out of the
inj pump. I tried again with the two levers on the side of the inj pump
in various positions but still only a very minimal amount of fuel. Am I
missing something?

Further I guess I should have some concern about cylinder surfaces. I
plan to run her abit, and if she doesn't overheat, do a leakdown test.
Any comments?
