Thanks for all advice, bled fuel line at injector pump, then at injectors.  
Started up and is now running.

If the fuel doesn't pump as David suggested, you might have to turn the engine 
a little.  Release the compression levers, and turn the engine a little by hand.

Re: Stus-List 3gm fuel issues

[Josh Muckley via CnC-List]

The reason the lever on the priming pump is more (or less) effective is
that as the engine crank position changes the cam that drives the lift pump
arm changes too.  If the engine happens to be at the peak of the lobe then
the lift pump arm will be fully actuated and the manual flipper will be
completely unfunctional.

Re: Stus-List 3gm fuel issues

[Josh Muckley via CnC-List]

Through years of experience with air leaks and low fuel I've learned how to
bleed my 3HM35F quickly.  On mine there is simply no need to touch any of
the bleed screws.  The entire system is almost self priming.  When I was
buying the boat we had a mechanic working on the engine and he said that he
never used the bleed screws, they strip out too easily.  Instead he uses
the banjo fittings.  This can be nearly as bad as stripping the bleed
screws since the banjo fittings rely on copper washer gaskets which are
supposed to be one time use.  That being said on multiple occasions one of
the bleed screws has come loose of been stripped resulting in an engine
shutdown and a scramble to establish control of the boat.  I now have the
culprit bleed screw epoxy puddied in place.  On the extremely unlikely
chance that I need to bleed I will loosen the banjo fitting.  In this case
it is the fitting that attaches the hard fuel pipe directly to the HP
injection pump.

Bear in mind that I have a second 3HM35F in my garage and have successfully
primed it without loosening fittings or bleed screws as well so my
experience with the boat isn't just a one off.

I have a priming bulb in the supply line from the tank.  It has much higher
capacity and as such works way better than the lift pump for
priming/bleeding the engine.  While you're trying to get the engine primed,
you should also be using the decompression levers to reduce load on the
starter and spin the engine faster.  This will get more fuel to the
injectors and faster.

Re: Stus-List 3gm fuel issues

[Dennis C. via CnC-List]

I may be full of baloney but, if I remember right, that lever operates the
engine's regular fuel pump manually.  When the engine is running, the pump
is operated by a cam in the engine.  If the engine stopped with the cam
oriented to push on the pump, then the manual lever will do little since
the pump is already pushed to max position.  Rotate the crankshaft a bit to
free up some operating room on the manually lever.

Hope I explained that clearly.
