    Sorry, no schematics for that in my shop. Is the harness all hacked up?

    If your wire harness is all hacked up it's going to be very hard to figure out where the wires came from or are routed to without a repair manual, or further research into your cars wiring.

    Fuel pump relay is on the firewall..

    Unfortunetly the schematic in the link provided is for the 305 not the 2.8l, so it's not going to help on this much but it's headed in the right dirrection.

    Try replacing the relay as they're pretty cheap and if it's original could use replaced anyways imo.

    I'm leaning towards your fuel pump being shot..

    The fuel pump is in your gas tank and complete replacements are available from most auto parts stores.

    But before that you should look into a repair manual for your car.

    If I recall, the chiltons for the 3rd gen contains wiring schematics that would greatly help if your harness is damaged.

    You may want to check out web sites for 3rd gen f-bodies as well. They could possibly have the schematics you need in more detail.
