When does the CIS cold start valve turn on?
If it’s like the CIS cold start valve circuit in the 930, it only operate until the thermo-time switch reaches 45 degrees…… ….I’d be looking at the cold control pressure first, so long as the CSV doesn’t dribble fuel when cranking, likely not the problem.
Is there a problem with the cold start valve on a 77?
I’d be looking at the cold control pressure first, so long as the CSV doesn’t dribble fuel when cranking, likely not the problem. ’77 S with ’78 930 power and a few other things. If it’s like the CIS cold start valve circuit in the 930, it only operate until the thermo-time switch reaches 45 degrees……
What’s the correct cold start valve for a Mercedes?
Here’s a picture of one though, might help. It’s even the correct one for your car, from Mercedes cold start valve 280 380 450 560 SE SEC SEL SL | eBay auction. See it’s got an electrical connector AND a fuel line?
How to check the Cold control pressure on a 930?
[QUOTE=spuggy;4793176]On a 930, powered off the solenoid circuit when the car is cranking only – and only if the thermo-time switch is below 45 degrees. As far as the CSV dribbling fuel; thats why my initial question is if anyone knows where it is located. Also, how would I check the cold control pressure?

Why is there no voltage to the cold start valve?
Sure enough Cold start Valve wasn’t pumping any fuel (this is while cranking the car over), and then when I hooked up my Multi-meter I didn’t get any Voltage outta the plug for the cold start either? Any ideas? What was the coolant temperature?
