if your fuel pump is cyclin it aint the relay...relay will not let it turn over or fuel pump wont work...but if you want to make sure either take them out and put them in your pocket for a while or hold a hair dryer on them if you can get one to them...but I don't think that is what it is...for the heck of it take your gas cap off and make sure you don't have a suction going on there...if you feel that you have a suction happening check your vent hose...also take a look at all your fuses too just to be safe....also not to talk down to ya but you sure there is enough gas in it...if you got the tail in the air and not much gas might be below the pick up line.
