i hve a 92 sc400 and i took out some aftermarket security systems and door lock control system and now it wont start. the fuel pump is not turning on. it ran ok before i pulled the aftermarket wiring out. im wondering if maybe the stock security system has enablen itself? i jumped the fuel pump on from 2 pins in the diagnostic connector and the car start and is moveable but has a code 13 and does not drive very well at all. im not sure where to start with this mess.
