the 90-93 accords are notorious for that problem. it is the EFI relay. it's underneath the dash, masked by some other gray relay. the relay i'm talking about is brown. the new part costs about 65 at a honda dealer but it can be easily fixed. what happens is that the solder is comming off the main board, so it won't make good contact, causing the car not too start. if u are handy hit a soldering gun you can save yourself $70. i gotta go look at my car cause i can't remeber how i took the stuff off.
