90tq Oil Pressure, Can't Prime Oil Pump

[Christopher Flanner]

Hello Listers,

I'm getting closer to the first start of my MC-1 in my '88 90q (see
http://www.teenaflanner.com/chris/90tq_turbo_conversion_gallery/).

Before I try to start it I want to make sure I'm getting oil pressure.  I
pumped 2 quarts of oil into one of the pressure switch holes to prime the
engine's oil pump and fill the passages.  I then cranked the engine (with
the spark plugs out) but still couldn't get enough pressure to open a 0.3
bar pressure switch.  I know the switch works because I tested it with a $7
hardware store drill powered pump (capable of 25 psi max.).  The switch
opened quickly with the drill at a very low speed.  So, I'm pretty sure the
engine's oil pump isn't pumping.

Any ideas?
