So I just installed my 255 pump its from high flow fuel systems ... I used a diy write up and everything was actually pretty simple I didn't damage anything ...so after installing .. I allow pump to whine 3 times snd then I turn it over to start .. at the instance I turn it .. the car feels like it wants to start .. but just shakes and continue to start as if it had.no gas . That's only after I let it whine a couple times .. I hsvr a little under half a tank of gas if its relevant
