I have a 04 mustang gt it sat up for a while decided to start driving it again now I'm having issues. It was acting like it wasn't getting fuel so I replaced the fuel pump got nothing. I replaced the relay control module under the passenger fender still nothing. The inertia switch is in the down position. Iv also checked the red and black wire going into the fuel pump control module I'm gettin power there. I'm at a loss on what to try next please if yall can help me out.
