Fuel pressure issue

So whenever I go and fill up my car with gas and i try and start it after, it dies and then i start it again and dies and it will only stay running if i give it gas. I need to do this for about a minute to build up enough enough pressure and then it doesnt do it again until i get gas again. So I would only assume that its the gas gap that is releasing the pressure but do you guys know why its not building up again fast enough like it should when the gap is back on?

Re: Fuel pressure issue

i'm also gonna assume its the gas cap as well. i'm just gonna take a stab in the dark and say something along the lines of things expand when they get warm, and it cools off enough while your getting gas, enough to give you problems for X amount of time.

Re: Fuel pressure issue

fuel pump is electric so it shouldnt matter about vacuume or pressure or anything, bad gas cap would only affect EVAP system. Dont really have an answer for you though. check fuel pressure and try replacing fuel filter.

Re: Fuel pressure issue

Re: Fuel pressure issue

my fuel pressure regulator is a B&M. If my fuel pressure is set to high on my regulator could that cause it to do that only when i fill up? I dont have a guage for the regulator yet so we have been kinda going by ear with the computer hooked up to it.
