Ok , so my wifes 2004 Grand Prix GT (not SC).. Has been hard to start for around 6 months... We hardly drive it so i havent gotten around to fix it... Takes on average 3 turns of the key to start it.. I know its a fuel problem.. Im assuming fuel pump.. i put a fuel gage on it and at idle it sitting around 54 psi, and once u turn off engine it drops to 0 within 30 seconds..
im confident its the pump, however i was wanting some other input just in case
thanks
