Default bonneville wont start

Has spark and fuel but won't start.Crank and cam sensors are good. My first attemt of trying to start if I hold pedal to the floor it starts and will bang off the rev limiter for as long as I hold it. I can let up and hammer it again and it will stay running as long as it doesn't drop below 3500 rpms. If I let it die it won't start again. Its flooding out but it has brand new regulater.I tested fuel pressure andits 55 with key in on position and if I get it to start its 55-65 as I'm flooring it from 3500 to redline (only way it will sta running) when I turn it offpressure will drop from 55-25 or so,so I relaced regulater again.same results.pulled fuel rail and turned key on no leaking injectors.help please

Mass air flow sensor was to blame.

When you post, it helps if you have the year/model of the car either in your signature or in the post.
