No start

At first, upon turning the key to on, it would crank just not start. After checking fuel pressure at the bleed valve I determined that fuel wasn't making it past the filter I've replaced that and still no fuel flow, upon the turn of the key. With the tip of my finger I applied pressure to the fuel pump relay to see if it was engaging and it seemed to be functioning. For whatever reason I pulled the relay out anyways but when I put it back and turn the ignition on the fuel pump relay clicks rapidly and the engine won't crank. Not kidding when I say, without my wheels I stand to lose just about everything that truly means something to me. Please advise me with the best of you knowledge. Thank you kindly, K.
