Cold Start Valve

Can't start on cold days, or are you having trouble with choppy starts and rough idling even when the weather's fine? If you've been driving for a while, or if you're a connoisseur of classic cars, these issues might sound a little too familiar. A persistent problem in older cars was getting the correct mixture of air and gasoline necessary to start the engine. You could easily flood out with too much gas by opening a choke too wide. You might also end up draining the battery trying to ignite a lean mixture. The reason most newer drivers have no knowledge of this automotive tribulation is simple: The addition of a cold start valve to the modern fuel injection system.

Also known as cold start injectors, cold start valves enrich your fuel-to-air mixture when your engine is operating at low temperatures. They're usually screwed to the intake manifold, where they use a thermometer reading to determine optimum operating conditions. They're constructed similarly to your other injector valves, with the major difference being that their injection time is usually measured on a different scale.

What is a cold start valve?

Your cold start valve is part of your vehicle's starter system. It's attached to the fuel injection apparatus. Like many of the other valves and related components in the starter system, cold start valves play an important role in getting your car up and running when the engine is stopped.

The cold start valve uses thermometric readings to know when to release more gas into the intake manifold and enrich the air-fuel ratio. This is necessary for cold starts and starting up in cold weather. A failed valve might keep you from starting up, or it might run too often and make you lose fuel efficiency.

How much is a replacement cold start valve?

The good news is that you might pay as little as $10 for new cold start valves. The slightly less happy news is that you could easily pay several hundred dollars. It depends on the type of valve you get, as well as what type of vehicle you're driving and where you buy your parts.

How do I replace a faulty cold start valve?

Cold start valves are mounted to the intake manifold. They're usually screwed in, making it relatively easy to get them out. One thing to note is that you may want to take your vehicle into a shop if your valve looks like it's rusted in or fused to the manifold. Take care when removing the old part. Try not to break any of the plastic washers or screws, and follow safety procedures.

Switching Your Cold Start Valve

1. Test for cold start injector failure. Proceed if you confirm your part is faulty.
2. Locate the valve on the manifold.
3. Disconnect electrical leads.
4. Loosen and unscrew your defective valve.
5. Carefully screw your new valve into the fuel rail.
6. Reconnect your electrical wires.
7. Place the key in the start position and let the injector run for a few moments before sparking the engine.
