T3: Further adventures in FI

[Schmitt@aerovironment.com (Schmitt, Frank)]

Over lunch I checked, as best I could, for vacuum leaks. This was suggested
by Greg.

There were indeed a couple of opportunities for air to get in at either end
of the pressure sensor tube. I installed/tightened a couple of hose clamps.
This still did not fix the problem.

I have some suspicions that I might have a really major air leak somewhere
in the intake manifold. With the fuel pump off, the engine is able to get up
to about 3500 RPM for a good 20 seconds. I can't imagine it could pump that
much air through the almost completely closed butterfly valve, and I don't
think it could run off the volume of air that is present in the manifold for
that long. I tried pinching off the hose that goes to that thing that sits
where a mechanical fuel pump would (I forget what it's called), but to no
avail.

Aside from the four big tubes to the cylinders, the one big tube to the air
cleaner, the small tube to the pressure sensor, and the slightly larger tube
to the thingy, is there anything else connected to the intake manifold that
could let in big quantities of air? Am I missing something?

Also, could someone diagram how the fuel injectors are supposed to sit in
their little holes? Is it easy to screw up installing them?

Thanks,
