Sounds like you have an ECM problem.

Run the KOEO test codes. See what shows up. You also need to check the SIGRTN circuit at the VIP connector. Key on it should show very little voltage. If it has 5v, then you have a short the Vref or a burnt SIGRTN circuit

No info about your car's model year, EFI or carb, no mods listed. Makes it hard to troubleshoot when we don't know what you have.

Therefore, no clue as to which wiring diagram you need. The wiring changed several times between 79 & 95.

That's why it is a good idea to use the sig under the user control panel (User CP) option. It allows you to post your car year & mods, which help greatly when troubleshooting things. No, it is not there for us to snoop and see any "Secrets" you have hidden away under the hood. Be a good stangnetter and update you sig for future reference & don't keep us guessing.
