94 Z28 Fuel Pump Diagnostic-Help
My Camaro started not wanting to start a while back. It cranks and gets spark but won't fire up and just kind of sputters for a second before dying. I tested my fuel pressure and it's around 38(ish)psi with the key on. I know that's lower than the 41-47 it should be getting but is it enough to make it crank/no start? The gauge was jumping more than I would think it should while cranking and the pressure drops off within a couple minutes (bad baffle in the fuel pump?). I can't smell gas or see a leak. I'm fairly certain I need a new pump, I just want to get a second opinion so I don't have to cut the panel and replace it in the snow for nothing. I'm considering the Racetronix 255 kit since I saw it well rated on another thread, though any suggestions on a better alternative would be appreciated.
Note: I bypassed the VATS system a couple weeks ago but I don't see how that could affect this.

That is plenty of pressure for the engine to start. Usually when a pump starts to go bad it will not act up until there is more fuel demand. So it will start, idle, and can be fine during cruising speeds, but will start to act up if you try and accelerate.
