Default low fuel pressure with key on???

posting for a friend.

it has 8psi then bleeds down to 0 and kind of sputters fuel/air out of the schraider. this is when key is turned on for pump to prime. pressure seems fine when car is running. but this make it hard to start.

bad pump?

check the connection from the pump to the fuel line in the tank. i had low psi and my
connection in the tank was jacked up.
