Every time I start my vehicle I have to start it right away. If I let it cycle through it will flood and not start. Wondering if it is the fuel pressure regulator or the pump?

Hi and thanks for using 2CarPros.

It does sound like a fuel pressure regulator issue. Here is a link that describes how to check fuel pressure and the regulator:

Fuel pressure specs are:

Key On Engine Off .................... 60-66 psi

Let me know what you find.
