This unofficial FAQ site at times uses input from random posters (like the
above) whose validity one _cannot_ judge. It's particularly annoying to note
that the FAQ credits a (definitely random) poster named "Oak" as
contributing this. In fact, Oak did not post this; some other person did,
per a groups.google search. It's not clear what this other person's
credentials are, either. I have not seen this test in official Honda
manuals.

Have you described this starting problem here yet?
Please do.
Does it occur on cold starts? After warmed up? After warmed up, then turned
off, then when re-starting, it doesn't start?
Is the engine RPM erratic at stop signs, with the engine running?
Does it seem like it's going to stall, and the only way to stop this seems
to be to hit the gas pedal?
How old is the coil on your 91 Accord? How old is the igniter? (Miles and
years, please.) Same question for spark plug wires and plugs.
For now, if the coil passes the test I posted, I would start looking at
other things.
Very common causes of early 90s (in particular) Honda no starts, assuming
fuel filter, air filter, plugs, and ignition wires are okay:
Bad main relay
Bad ignition switch
Bad distributor ignitor
Bad distributor coil
There is a test for the ignitor at the autozone site I gave earlier.
You might get some ideas from the unoffical FAQ site, but I would not bank
on its advice (if you can quickly extract it from all the painfully not cute
colloquialisms that pollute it).
Hang in there. I'm sure some of the regulars will leap in and offer further
suggestions. For now, use the online manual at Autozone and try some of its
tests.
