1991 won't start when it's been in the heat for a while

fuel flood, kinda like a carb does,but in this case it sounds like the fuel presure in the line is bypassing the seal,just check your fuel injector seals.I had my 1992 GS-R since 1998 I never had an issue with main fuel relay its just a stupid myth.

It's not a myth, it's a known problem...but I suppose you know more about Integras than everyone here who has had this issue, and the Honda Master Techs I worked with. I'm sure it's more likely the less common problem you suggested than the common, known problem that you claim is myth.:roll:

try doing the easy things first. replace the relay and than go from there instead making things hard go easy and than find out. mine had the exact same issue. i replaced the relay and it runs like the day we bought it. do the relay to save time and money and if its not the relay, well that means one less spot you have to check later

Same issue several weeks ago, resoldered the cracked points and fine now.
