Hi,

If the pump isn't turning on, chances are it's an electrical issue. You indicated the fuses and relay are good. Did you confirm power to both?

As far as determining the cause, I attached the diagnostics for the fuel pump electrical circuit. Take a look through the directions and let me know if you are comfortable performing them. Also, let me know if you have questions.

Here is a link you may find helpful as well:

Take care and let me know what you find.
