My Fuel problem 5.3 swap
I'm having issues on my 5.3 swap into my 1966 c10 as soon as I switch the key the fuel pressure gauge jumps to the maximum psi on the gauge (over100) the truck starts up but after a few seconds it starts dying out and the pedal becomes in responsive (DBW) after that the pedal won't work again unless I continually flip the key on and off till the pedal works again , and once again the truck starts up fine but then accelerates really high only to idle really low and die out , I'm running a walbro 255 , corvette fuel filter /regulator combo , stock injectors and aftermarket fuel rail , when I turn the truck off the fuel pressure slowly starts dropping from over the 100 psi mark till about 45 then stays there for a while and drops more

2001 suburban 5.3 all stock internals except for cam , tuned by black bear performance , stand alone with speed density tune to eliminate maf sensor due to set up , stand alone wiring , at first I thought the gauge was faulty but this is the second new gauge I've bought and does the same thing
