Acura starting problem

Seems like this is a prominent problem with Acura's but I have a '94 Integra that starts fine when cold, but once I turn it off I have to wait for the car to cool down to start it again. The starter cranks and it seems to have plenty of battery power. The car just seems like it isn't getting any fuel. From all my searching I have determined that the most likely culprit is the main relay - which I believe I can replace if I could just find someone who can tell me how to find it or direct me a diagram of where it is. One internet link I found stated that it was attached to the fuse box - which is under the hood. I couldn't find it there. I have read other places that it is under the dash close to the steering wheel. Sure would appreciate any help I could get. TIA - LizCar Repair Talk's forum.
