cold start system does not work . i have changed c/s inj. time switch, coolant temp. sensor (2 wire next to c/s inj.time switch ) connector on c/s inj.time switch was broken, so got new connector cap, but wires may have been installed backwards . when key is turned to start, 4volts in black / white striped wire. when cold (at 35 degrees) when hot, 12 volts at b/w wire when b/w wire @ c/s injector is grounded to battery. c/s injector works when wire with 12 volts is connected , & ignition switch is activated .
