    you know what I don't see that fuse link wire... and I believe that's the wire I was told fried so it would make sense that this yellow wire would be the one in question. Did this fusible link get it's constant 12v from being bolted directly to the starter solenoid or somewhere else?

    Schematic is for a 92. See if it matches what you have. Ford like to change wiring colors.
    See fuselink G.

    Well 99% sure that yellow wire was the VPWR wire to the ECC relay so I attached it to the starter solenoid with a new fuse link and everything works again except the fuel pump will not prime. Tried another fuel pump relay but no dice.. it seems the ecc relay is the same relay so I tried the new one in there and no dice neither. Im getting volts to the inherta switch and fuel pump

    See the Fuel pump Troubleshooter tech note I posted earlier. It has everything you need to know to troubleshoot and fix your problem.
