I posted a question regarding no-spark on a '91 Accord last week.
Problem solved:  It was the coil.  That is so strange considering the
car ran when parked.  I figured a bad coil would cause a breakdown, not
a no-start.

Diagnosis went like this (steps 1-5 done before the last post):

1.  Key on causes fuel pump to cycle.  Thus, ECM probably okay.

2.  Checked spark at a cylinder - nothing.

3.  Verified cam was turning through oil filler cap:  Cam turns, timing
belt must be okay.

4.  Removed cap, checked spark from coil high tension post:  Nothing.

5.  Checked coil resistance - .7 ohms low side, 12k ohms high side
(disregard last post on this - I measured the high side incorrectly).
Note:  These readings are in-spec!

6.  Removed ignitor from distributor and performed bench test procedure
from tegger.com - Passed!

7.  Bench tested the coil:  No spark from high side to ground - BUT,
just enough to cause a mild shock from high side to _positive_ terminal
of low side.  Looks like a bad coil.

8.  Connected small light bulb in place of the coil and cranked the
engine:  Light flashes.

Number 8 was what finally convinced me to replace the coil.  Installed
a new one and the engine fired right up.  I went ahead and replaced the
cap, rotor, plugs, and wires because their condition undoubtedly caused
the problem to begin with.

Thanks Elle, Jim Yanik, Thom, motsco, and Tegger!
