Paul,
If your ignition system shuts off the pump with no
spark, isn't the following going to happen?
Pump 1 on -- engine running,
pump 1 fuse blows, engine shuts down very
quickly,
Pump 2 turned on, but no spark since engine has
stopped, therefore it shuts off right away.
Sounds like if engine stops, you have to crank it
to get it started again

Turned on the other pump, but
the engine had already quit. (yes, it happens very
fast)
I now recall
reading in the MicroTech manual that the fuel pumps shut off if it detects no
spark from the coils, so that it would not continue pumping fuel into an
engine that has no spark. This is obviously why the pump only runs for a few
seconds when I first turn on the ignition switch, then quickly stops pumping.
We put a voltmeter to the inline fuse, and found that it had 12.9 volts as
soon as the ignition was turned on, but after a few seconds, the pump stopped
and there was no longer any voltage at the fuse.
I'm hoping we can find what
caused the slight fuel obstruction in front of the gascolator....if we can't
find the cause, it would be difficult to regain confidence in the fuel system.
Too bad, because the engine was running strong and smooth, and the temps were
great!!! Paul aka deadstick Conner
