Eric, welcome aboard!!

First off, your ECU is not a likely culprit in this case. You have
stated that you have fuel but no spark. The ECU controls the fuel
injection system and is not in the igintion circuit anywhere. If you had
any spark at all in the presence of fuel/air, you would certainly get
some kind of reaction from the engine.

 You have fuel and air but no ignition. If it is stone cold dead and
won't go, the Hall sensor which is mounted on the back of the
distributor is the number one suspect. Check for a loose connection
there. Loose wire, broken wire, connector pulled loose from the wire
itself. But also check all the wiring .... grounds, and coil wire
particularly.

If you are getting no fire from the coil, period, I would thing it would
be the Temp II sensor, and that feeds back to the ECU, and again it
becomes a fuel injection - fuel/air issue, which is not what you seem to
be having.

Do you have a Bentley. If not, get one. Helps a lot, though not perfect.

Good luck,

Regards,
