Default fuel pressure takes a while to build at start up?!

hey guys. i've got a hard start problem. what i just noticed is that the fuel pressure when i crank the car cold will be at zero and then slowly rise up till it reaches optimal pressure and starts. any ideas what this could be? is this a distinctive symptom? thanks.

Default 2nd

Mine suffers from the same notorious problem. Usually cranks but won't start the first time, especially when warm. A second turn of the key and it fires up right away. I have a new check valve sitting on the shelf waiting to be installed when I get a moment.

Maybe fuel accumulator? Not sure if these cars have the same system, but that happened to my 4KQ...

Default more symptoms

so alongside that the car has to build up pressure, as soon as i shut off the car, within seconds, i lose ALL fuel pressure. I also have less overall pressure while driving too.
