Newbie here,

04 grand prix gt. 3800 series 3.

it will only do it once and a while. maybe twice a week. turn key... start..die rite away. it doesnt even run 2 seconds. but if i give it gas and turn it it will start no problem. its very intermitten .

one time when it happened it took 3 times before it started. but gave it gas and fired rite up

i replaced the fuel filter and air filter. i think my next step will be mass air flow sensor cleaning...throttol body cleaning and some fuel injector cleaner.

anyone else have any suggestions? possible fuel pump bleeding down?

You're headed in the right direction with that, in that order. Actually do the mass air flow sensor and TB at the same time since you're already there.
