your injectors are leaking,that test failed, the key off leak down test, it just holds or the injectors are leaking or the check valve in the fuel pump is stuck open, (or rusted)
key on , 3 times (unless lines were opened) key on 3 or many times if lines were open, and pressure must be 36 minimum..
the start car and the key on pressure what ever it was. must drop (FPreg action -vacuum caused)
that starting at 0psi is wrong, i bet you have a gauge issue, or the one of the schrader valves in the line are stuck closes. on mine there is one valve mid line that loves to do that trick.,
you can hear the pump run for 3 seconds, each key on. and the gauge must rise some, for it would not ever start.
most injectors are dead up to 20 psi.
watch out for the mid line valve. it's finicky,
if the pressure is good, running
we check the maf voltage next.
