Takes multiple key turns to start

Hello, You may just have an issue keeping fuel pressure. When you go to start it next, instead turning the key to crank, then off, then crank, then off until it starts, do that same thing but only turn the key to the on position, like this : on, 10 seconds, off (key out), on 10 seconds, start. If it cranks up after this, have the fuel pressure tested to see if pressure is bleeding off when the pump stops running.
