Installed fuel pump and still will not start. I was told the relay is integrated into fuse box under dash and was told fuse box will need replaced.

Hello, I am Danny.

Have you checked the fuel pressure after installing the pump? I have attached a link how to test. Most auto parts stores have a tool loaner program to loan/rent the tester. Your vehicle should have 35-45 PSI. Hope this helps and feel free to ask any questions if needed. I can also include specifications of diagrams if needed. Thanks for using 2CarPros.

There is a fuel pump relay located in the fuse panel under the hood. Here is a guide to help you test it:
