Yep, yep. And I get fuel out of the relief valve when I push it. But it is a 0-100, so since the 50psi marker is only bout a half inch above zero. So maybe there's enough pressure to start, but not to read?

Screw it on nice and tight, and just cycle the key a few times, to make the fuel pump run repeatedly. See if the needle does anything at all.

Alright, well scratch that 1/2in thing I was talking about if you ain't already. I was looking at the wrong side, 100psi gauge, obviously 50 alot more then a 1/2in! But I did finally get her to move, All be it not very much, she's chilling at about 4 or 5psi, so fuel pump?

If the regulator is in the fuel pump (I think it is for the 2nd gens) and you have no constrictions, you could pull the pump and see whats up. Pickup might be clogged in the tank, or the mechanism just doesn't have any life in it. Pulling the pump out isn't easy, because the bed tends to be in the way of removing the pump from the tank. Lots of workarounds on this site... some people cut a hole in the bed, some unbolt the bed and just loosen the rear bolts, and lift that end with an engine crane, etc....

It sure is and yeah, I've always been afan of the hole cutting thing? But if it still sounds like a pump then id have to pull it out anyways, might as well give it a look before putting a new one in. But AutoZone wants 150 for the cheapest so If I need one it'll be from Amazon, 50bucks with a two year warranty so it'll be a few days before I get it. How would I know if it's the regulator or pump?

If you enjoy changing fuel pumps, buy the cheap one. If you only want to do the job one, get a denso, or delphi pump. Yeah, its significantly more expensive, but, change it once, and don't worry about it again.

Believe me, I know you get what you pay for and I appreciate the heads up. But I plan up swapping out this year so I'm hoping itll last long enough! And I'll let y'all know how it goes.
