What does a cold start valve do?
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 engines not start in cold?
When it’s cold, engine oil becomes thicker and doesn’t flow around the engine as well. In the rare event that there’s moisture in the fuel lines, this can freeze and cause a fuel blockage, meaning the engine won’t start. This is particularly common in the fuel lines, which are thin and easily blocked by ice.
What is a cold start on a computer?
Cold start in computing refers to a problem where a system or its part was created or restarted and is not working at its normal operation. The problem can be related to initialising internal objects or populating cache or starting up subsystems.
Can a car not start because of the cold?
Cold batteries simply don’t produce the same amount of power as warm batteries, and this effect can lead to starting issues. When it’s cold, engine oil becomes thicker and doesn’t flow around the engine as well. If the battery is already low on power, this can result in a non-starter.
How to adjust the timing in a 1993 Toyota Camry?
Adjusting the timing in your 1993 Toyota Camry as part of a tune up will compensate for engine wear that causes small changes in the ignition timing that cause poor fuel economy and loss of power. The average home mechanic will take about 30 minutes to complete this project.
Where is the spark plug on a 1993 Camry?
In the 1993 Camry the number one spark plug wire is the closest to the passenger side fender. Start the engine. Point the timing light at the timing marks on the front of the engine’s timing cover and note the position of the notch on the crankshaft pulley below it. Loosen the 12mm distributor nuts using a wrench.
What does ignition timing on a Toyota Camry mean?
The term ignition timing refers to the position of the crankshaft (measured in degrees of rotation) when the number one spark plug it fired to ignite the air/fuel mixture in the cylinder.
