Re: Thermo Time Switch

Thank you Robert, it starts to make sense now, but I'm still not quite sure.

I'm having problems with cold starting. Warm starts are perfect. At the
first crank, the engine starts very eager, but after 2 or three seconds, the
engine starts stalling en after 15 seconds or so, it stops. This is repeated
for 3 cranks and then the car idles fine. After a minute or 4 the engine
temperature rises and the car starts to run normally.

Keeping this I figure that the cold start valve works fine but that the
thermo time switch might be the culprit. Looking at the schematics I thought
that the cold start valve is correctly operating while cranking, but not
during the first minutes (while the engine is still cold).

I suspect that the fuel accumulator and cold start value are working
correctly because the engine starts very eagerly while cranking. I remember
inspecting the connection to the thermo time switch when I bought the car
and putting it back the same way as I got it out. (I checked this because my
car has always had this problem).

YES! It does mater which way the wires are plugged into the thermo
time switch. When looking at the schematic of the tt switch and the
cold start valve, you'll see that both are connected together with 2
wires, and that the tt switch also has a ground connection. Plus the
cold start circuit is tied into the starter, so this circuit will
only be active durring engine cranking.
