i've never had any problems with any relays but a friend had to replace a fuel pump relay in his 95 civic once and the mechanic told that sometimes they get stuck and you can bang on the dash to make it work until it gets stuck again. I would check to see if your getting fuel first,if not,then replace relay's or fuel pump,etc. if you pop up the lower section of the back seats and and remove the gas tank access cover you'll find,the pump and sending unit attached together. take the fuel pump and stick an ohm meter on it to find out if its working or not. or just turn the key on and listen to it.
