Accord 91 Won't start when it's hot

Hi group,

I have a honda Accord 91 LX and sometimes it just refuses to start in the
summer when it's hot and humid; and I'm in Texas so it's not very helpful.

The batterie is brand new so it's not the problem, when I try to start it I
hear the starter, but it just doesn't start. I've never had this problem
during cold weather, but when it's sitting in the sun in summer, especially
when it's humid (we had 2 inches of rain last night), sometimes it refuses
to start, like right now. What could be the problem? A guy at the garage
mentionned maybe a gaz relay thing or something like that. One day I had
this problem in houston and I just opened the doors for 10 minutes and I was
able to start after that. But today, no luck.

Thanks in advance for your ideas.

================

Replace or just resolder your MAIN RELAY. If you turn the key to II, and
don't hear the fuel pump run for two seconds, try smacking the dash . .
.. If you hear the pump run, it will probably start.

sounds like the main relay going out.

you've cited common symptoms of the main relay's failure.

-check the rotor cap for cracks, replace if necc ($10)
-replace main relay with used or new part ($5 used, $50 new)

good luck.
