for other diagnostics, go to tegger.com and check out the no-start
faq's. despite your main relay test, intermittent no-start usually /is/
main relay in my experience, especially for a civic/crx this age.
usually accompanied by a code 16 though. re-soldering is cheap if you
have the tool. i recommend properly de-soldering to make sure all the
old detritus is removed before re-soldering. '89 crx main relay
location and removal is the same as the 88-91 civic which is very well
covered in tegger's faq's.

sounds dumb, but you could also try changing the plugs. i was /given/ a
free civic last year by someone that had spent a fortune hunting down a
no-start just like yours. a new [used] set of plugs and it roared into
life! don't use bosch, use factory ngk's.

when testing spark leads with an old plug, open the gap right up -
sparking distance is different at atmospheric pressure vs. cylinder
compression pressure.
