How about this for a kill circuit. If you know where the relay is for the pump control all you would have to do is put a switch in series with either of the two relay coil wires. This is a low current circuit and would not require a special switch to handle heavy current. If one wire was tied to ground I would choose that one to add the switch into. This would do what you want to do. What do you think?

According to my 88 manual the relay is in a blue socket and may be on the right side of the steering column under the dash. The coil wires are colored blue/white and blue/black. It looks like they are series in with other items so there is some extra current that they are carrying. The blue/black wire looks like it would be the best to break into. If you had a switch that could handle 10 amps that should be ok. Most micro switches can handle that amount. I doubt that it will be that much anyways.

 

There are some other relays in the area also so don't confuse it with another one. When you first turn the key to the on position you should be able to hear the fuel pump turn on briefly. You may have to cycle the engine to hear it again. You can pull the relay you suspect is the right one and listen for the pump. If you don't hear it then you most likely got the right one.
