Had repaired along with dirty fuel filter the fuel injector was bad. Would work long enough to start then quit. $140.00 to fix
If it is a echo there is a switch. If it is on cold start switch it to run unless it is cold then you should switch it to cold start. There is also a silver switch that you have to flip up.
Many possible reasons. Maybe cold start switch(valve) is bad.

A thermo time switch is a temperature sensor device normally used to turn on a cold start injector in German cars. The cold start injector is an extra injector normally mounted in the intake manifold. The thermo time switch will allow current through it to your cold start injector for a few seconds ( 3 - 8 depending on the make and model of car ) when the engine is cold and first started. This puts extra fuel in the system and helps it start. If your thermo time switch fails you may have a hard time starting when cold or, more commonly, a difficult time starting the car when hot. The problem in the latter case is the extra injector flooding the car when trying to start it.
Check your battery first.. If it is fine, you might need to replace your cold start injector timing switch. Fairly expensive, but should work.
Change CHT sensor=Cylinder Heat Termo switch
The cold start sensor is the top sensor on the right side of the thermostat housing as you are looking at the engine from the front of the vehicle. It is 22mm.
this could be due to a faulty cold start injector, or cold start injector time switch. Could also be caused by incorrect valve adjustment.
Cold Start Valve. Cold start valve. I do not believe there exists a "cold start valve"
1994 Skylark v6 3100 motor Mostly when it's cold it won't start, cranks over good it seems but don't seem to fire. Every once in a while it sounds like it going to start and then just keeps cranking over. Some one told me to try the oxygen sensor well I found out there are two of them and there $70 ea. Also someone else told me to replace the Ignition coil or the Ignition sensor. What do you think?
cold start switch on the side of or on top of the throttle body.
