93 ex won't start on hot afternoons - help!

i need help with my 93 civic ex coupe, 230k miles, manual trans., i'm the original owner.

live in new england. starting last week, warm temp. afternoons (80+) after work (5pm+), car won't start. plenty of charge, can't seem to get gas. leave it, try again in morning when cooler, starts right up.

had been a long while between tuneups so had that done. was cool for the next 5 days until last night, when it was again over 80 degrees - same thing - can't seem to get any fuel. again, started right up this morning.

need to get it to my mechanic, but want to tell him all this without thinking I'm a dope. so, has anyone ever heard of this happening, and if so, what it turned out to be? obviously, the car has been great for me for over 11 years and it's probably nearing the end, don't want to put too much $ into it but want it fixed.

i need help, quick! thanks to all.

Hey man! It's a thing called your Master main relay i belive.. when it get's to hott your car wont start. Id get a new one from a junkyard or something. when mine wont start i just push it down a street and pop the clutch and it starts right up!>


Hope it helps man

does it turn over? If it turns over next time it wont start try sprating carb cleaner into throttle body if it fires you know its a fuel problem when its cool and starts does it crank a long time if so might be that fuel pump bleeds off pressure causing vapor lock
