I get about 10.5 v
That would be about what I would expect to see with the starter turning the motor at the same time and engine not running.
Like daveson mentioned, keep going with Berts flow chart.
I'm asking the following for clarification, to make sure we didn't miss something.
In your 1st post you mentioned 36psi fuel pressure(which is good), where did you measure this and how. A gauge tapped into the actual line, or just plugged into the end of the hose coming out of the fuel tank.
When was the last time the fuel filter was changed..... A restricted filter can allow static pressure to build to closed injectors but then when they open and relieve the pressure there would not be enough flow to do any good.
A bad fuel pressure regulator can also cause you grief.
