CIS Cold Starting Solution
 

Is your thermotime switch correctly connected?

The thermotime switch is mounted on the left cam chain cover near the engine electrical master plug. It opens your cold start injector when the engine is cranking. It's a switch so you just connect the two wires; wrong! It is internally grounded so one connector is the switch and the other is the heater to turn it off. The red/black wire must go to the switch (0 ohms to ground when cold) and the yellow to the heater (mine is about 60 ohms cold). If you connect it wrong the cold start valve will not open because its in series with the high resistance heater and you will have starting problems.
