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 and additional fuel is required.

Why do cold start problems occur?
New item. The item cold-start problem refers to when items added to the catalogue have either none or very little interactions. This constitutes a problem mainly for collaborative filtering algorithms due to the fact that they rely on the item’s interactions to make recommendations.
Can a temp sensor affect engine starting?
If the sensor is reading too high of temperature when compared to the ambient air temperature sensor when first started then the computer would see it as a problem and turn on the check engine light to use a known good reading. No start will not be caused by the sensor.
What is a cold start solenoid?
The cold-start solenoid is the rear most solenoid on the fuel injection pump, closest to the starter motor, and is powered directly off of the starter solenoid. It is only activated when the key is in the “start” position and the starter motor is engaged.
Why is my car cranking but not starting cold weather?
In cold weather, engine oil thickens and doesn’t flow as well.
