Power to the fuel pump is from the ASD relay which is part of the PM on 85-87, check the wiring from the ASD to the pump, the fuel pump ground is external.
Locate the underhood diagnostic connector and with the key on/engine off ground the DB/YL wire, this will actuate the ASD relay so you can check the power output.
Why are you ignoring your TPS code. If the fault is voltage high the injectors will not be actuated, TPS voltage that is 2.43 volts over minimum will cause the controller to go into clear flood mode.
