85 Daytona turbo, fuel pump and car will run when the fuel pump is powered from an external source. Codes are 12, [normal], 23, TB temp circuit, 24 Throttle position circuit, and 32?????. No clue of what that one is. Anyone
else know? I obviously have power every where else in the Z1 circuit so I am stumped! Thanks in advance, Greg

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.
DR-12 Fault Code 32 Power Loss Lamp Circuit
Place ignition switch in Off position, then disconnect logic module blue electrical connector.
Place ignition switch in Run position, then connect a jumper wire between logic module blue electrical connector terminal No. 4 and ground.
If power loss lamp is illuminated, replace logic module.
CAUTION: Before replacing the logic module make sure the terminal in cavity No. 4 is not crushed so that it cannot touch the logic module pin.
If power loss lamp is not illuminated, check bulb and power loss lamp wiring.

Hey NAJ, checked everything out per your suggetions and she is all clear on faults and running great. Turned out to be a fairly minor wiring issue. Thanks again, Greg
