Alright, so been having this problem like once every two weeks, now it's everyday...
Sometimes it'll start up fine, I hear the pump prime, sometimes, i won't hear it at all, or it comes on at a delayed time for a split second.... Bad relay perhaps? I was reading online about how the fuel pump relay runs when the motor's off but than switchs to the oil pressure sending unit after the motor's running, huh?

Anyways.. Little shot I took to. 2nd start, fuel pump primes for a split second 3 seconds after I turn the key on but not starting it.

I didn't see an issue .. it's supposed to prime once you turn the key.. before the engine starts?
 






It does prime once. THat 2nd start, it came on 3 seconds AFTER i turned the key, whereas it's supposed to be when I turn the key to on.
2nd start, 3 seconds after turning key on and only for a split second.
 






Are you talking about the extremely low idle on 2nd start? That's about the only thing I notice/hear in the video.. I'm at a loss of anything else.. unless I actually can Hear the prime.. I have no idea whats going on.. it could just be the relay?

Edit: Oh you mentioned that, try replacing that.. it's the cheapest and easiest thing to do at the moment.
 






Yes, I should've placed the cam down by the ground, oopsie. Lol.
When it gives me a no start issue, I usualy pull the relay, put it back in and starts right up!
 






Relay finally took a crap on me. lol, replaced and all's good
