When does the cold start valve receive power?
When you turn the key to start (the cold start valve ALWAYS receives power when the key is in start, and ONLY when the key is in the start position — temperature is irrelevant as far as the cold start valve itself is concerned) 12v is sent to the cold start valve.
Why is the cold start valve open on an air compressor?
When the air compressor starts, the cold start valve is open, and has allowed any trapped air from over the piston to escape when the last air compressing cycle was completed. While air can escape out of the cold start valve on start up, it cannot escape (usually) as fast as pressure can be built by the pump.
What to do if your cold start valve is leaking?
Your cold start valve may be clogged. No initial burst of fuel is reaching the engine. To fix: Find and clear the clog in the cold start valve. The cold start valve is leaking, sending too much fuel at start-up. To fix: Find and fix the leak, or replace the cold start valve.
When does the thermo time switch shut off cold start?
When the key is “on” the heating element in the thermo-time switch is warming up and slowly bending the contact arm, and so once it gets warm enough, it breaks contact and no longer grounds the cold start valve, shutting it off. However, this applies only when cranking.
How to fix a faulty cold start valve?
To fix: reduce the thermometer start interval to between 2 and 5 seconds. Your cold start valve may be clogged. No initial burst of fuel is reaching the engine. To fix: Find and clear the clog in the cold start valve. The cold start valve is leaking, sending too much fuel at start-up. To fix: Find and fix the leak, or replace the cold start valve.

What is the purpose of the cold start injector?
The cold start injector, also referred to as the cold start valve, is an engine management component found on many road going vehicles. It’s purpose is to supply the engine with additional fuel to enrich the fuel mixture in cold temperatures where air density is increased…
