Barrett,
The tach signal comes off of the coil so logicaly you would think that is a
valid test of the Hall sensor. BUT, I do not believe the starter can turn
the engine over at 1k rpm.
Have you checked the fuel pressure? I permanenty installed a gauge in the
engine compartment for under $20. See web page. In your case I can not see
how fuel pressure could be intermittent but stranger things have happened.
I tested the sensor by turning on the ignition and rotating the crank by
hand. Every time the Hall fires it causes the injectors to fire, which are
easy to hear. Pull out the center coil wire so the engine doesn't kick start
while your fingers are in there.
I would also unplug either the O2 or TEMPII sensors the next time it
malfunctions.
How are the grounds between chassis and engine? Check the voltage drop there
with all electrical consumers on. Should be less than .2 volts. There is
also a ground wire in the bundle going to the Hall that fails frequently, or
so I have read here. Check archives.
Good Luck.
