Hello again.

Like you stated I would suggest checking your fuel pressure. Your in tank pump could be weak/failing/low on pressure. I am attaching a tutorial that shows what is involved in testing your fuel pump. If you do not have access to one, your local auto parts stores have a tool loaner program an can rent you one. The output fuel pressure on your car should be between 51-62 P.S.I. Hope this helps and thanks for using 2CarPros.
