    See this FIG : Fig. 12: 1986 Pickup engine controls w/fuel injection

    The injectors A & B are connected to the ECM and the mixture heater relay. The relay is still engaged or stuck and it was the cause of the injectors ( TBI ) stay powered.
    The relay is connected to the battery ( hot all times ).
