car won't start when it is over 65 outside

Resolder the main relay. Very common.

I have a buddy at work who had the exact same issue with his early 90s Accord a couple years back and had a $100 part replaced that fixed the problem. Likely what Steve posted here. I'll check with him tomorrow and post back.

Main relay? enables the fuel pump to keep enough pressure to run the fuel injection. Has problems with cold solder joints,causes intermittent operation,heat-related.

If you need to use the car tomorrow, before fixing the relay, you can smack the dash with the switch in position II, and you'll hear the fuel pump run for four or five seconds . . The car will now start. When the car is warm, it's the vibration that keeps it going once the engine starts.

After you got all the good replies, here's something that made me wonder...

Where in the world do you live that 65 degrees (assuming Fahrenheit) is considered *hot outside*? ;)

LOL

Yep, I asked my buddy today and the main relay issue mentioned by several people here is exactly what he had fixed a couple years back.

Thank you for the info on my problem. I spoke to a Honda tech and he told me basically the same thing. Oh yeah, in upstate New York 65 is a beautiful day.

Put a new relay in and it could fail in the same way.No way of telling how old the relay is. Resolder the one you have,and you save money.

Ya, he didn't say whether he had it replaced or repaired, although most likely replaced taking it to a mechanic. It's been ok for a couple years now, but your point is well taken.

Sometimes the contacts get funky. I resoldered the one in my daughter's '93 Accord and it remained intermittent. A new one fixed the problem.

But at least you didn't blindly replace the relay. The cost to resolder is negligible,replace a working relay that wasn't the problem and you're out $50-100.

The cost to resolder is negligible IF you do it yourself. If you're part of the other 98% of the population who pay someone else to fix their automotive problems, nothing comes cheap. If you are part of that 98%, you probably shouldn't be driving a 15 year old vehicle though.

Ain't that the trooth.

With an older car, you've got to accept that you'll be doing lots of little jobs all the time, and raising the hood at least once a week.

You'll be on the constant lookout for sudden increases in oil consumption, leaks, rattles and other weird noises, rust, failed parts that are not obvious, all sorts of stuff.

You'll also be comparing the cost of fixing the old car to the cost of carrying a new one, and you'll be willing to let your neighbors think you're crazy for spending lots of money keeping an old car in good shape.

You'll allow yourself a budget, say $100 per month (or more), for repairs, and will not skimp when it comes to fixing things right. And your neighbors will think you're crazy.

You'll hang on to the old car for lots of personal reasons, none of which anybody will ever understand, except another nut like yourself (or maybe your wife).

And you'd be amazed how cheap an old car is to run when you don't try to cheap out on repairs and maintenance, even if you get somebody else to do the hard stuff. An old car is hobby. If you don't want it to be a hobby, stick to somethng new.

Could not have said it better myself...
