The clicking you hear from that relay box is normal. You normally just don't hear it because the sound of the engine starting drowns it out. Are you getting spark? You can pull a spark plug out, put the plug wire back on it, and carefully hold it to the block whild someone cranks the car (make sure to only touch the rubber boot of the plug wire). You should see the plug firing. Also, when you put the key to the "ON" position, you should be able to hear your fuel pump. If you don't hear a slight whine coming from the back of the car, the pump might be dead (you might want to have a friend turn the car on while you listen carefully at the back of the car). Also, if you pull the plug out after trying to start it a few times...and the plug is wet with fuel...you know you're getting fuel but there's no spark.
