A cold start injector is a component in some internal combustion engines that helps improve engine performance during cold starts. It delivers additional fuel to the engine when it is cold, ensuring a richer air-fuel mixture for easier ignition and smoother operation. This extra fuel compensates for the reduced vaporization of gasoline at lower temperatures, aiding in a quicker warm-up and reducing emissions during the initial start-up phase. Once the engine reaches a certain temperature, the cold start injector typically shuts off.
What else can I help you with?
I have a Cold start problem with a 89 Camry 2.0 what can it be?
It can be battery, faulty coolant temperature sensor, faulty cold start injector, malfunctioning fuel system, injector leaking.
Does a 2000 Dodge Ram 1500 have a cold start injector?
No.
What could cause a 1991 Celica ST to be difficult to start when cold then starts quick all day but the idle is too high?
this could be due to a faulty cold start injector, or cold start injector time switch. Could also be caused by incorrect valve adjustment.
1993 Mazda 626 is hard to start when its cold?
maybe weak battery or an injector component is defective ( the additional injector that gives extra fuel to start the car )
What is a Thermo Time Switch?
A thermo time switch is a temperature sensor device normally used to turn on a cold start injector in German cars. The cold start injector is an extra injector normally mounted in the intake manifold. The thermo time switch will allow current through it to your cold start injector for a few seconds ( 3 - 8 depending on the make and model of car ) when the engine is cold and first started. This puts extra fuel in the system and helps it start. If your thermo time switch fails you may have a hard time starting when cold or, more commonly, a difficult time starting the car when hot. The problem in the latter case is the extra injector flooding the car when trying to start it.
Does a stock 85 Pontiac fiero gt have a fuel injector?
This engine will have seven injectors. 6 are the running injectors and there is a "Cold Start" injector.
What is the cold start pipe on the 1987 pontiac fiero gt fuel rail?
There is a high pressure fuel line under the throttle body that carries fuel to the cold start injector. There is a black pipe that feeds idle air to the same spot to insure the cold start injector gets a good mixture.
Where does the cold start injector get its pulse on a 1992 E 300 4matic?
In a 1992 E 300 4Matic, the cold start injector receives its pulse from the engine control unit (ECU). The ECU monitors engine temperature through the coolant temperature sensor and activates the cold start injector when the engine is cold, providing additional fuel to aid in starting. This process typically occurs during the initial cranking of the engine to ensure smooth ignition under cold conditions.
What are common causes of no start when fuel relay is good for 1996 Honda civic?
Have the cold start injector checked
What is a cold start injector on a 1986 Honda CRX?
The cold start injector does what the name implies. When you first turn the key to start (on a cold engine) the CSI gives the engine a richer mixture by injecting fuel into the intake manifold while the starter is engaged so it starts faster/easier. How long the cold start injector runs depends on the temperature. (Usually only a few seconds). There isn't a cold-start injector on your car. The cold-start injector, aka the "fifth injector," is a relic of the Bosch K-Jetronic fuel injection system. This was designed in the 1960s and is essentially mechanical. On the K-Jetronic, when the Cylinder Head Temperature sensor detected the engine was below a certain operating temp, it would inject fuel into the throttle body. Think of it as a fancy choke. Cold-start injectors have one huge problem in today's emissions-paranoid climate: all that extra fuel generates extra pollution. That will not do. Honda uses a cold-advance solenoid valve in 1986 cars. There is a cable connecting it to the FI computer, and a vacuum hose connecting it to the distributor. (For all you guys who ever wondered why there are TWO hoses going into the vacuum advance on a Honda distributor when most cars only have one...well, this is why.) When the engine is below operating temperature, the cold-advance solenoid draws vacuum on the distributor, which advances the timing and makes the engine run faster without all the smog a cold-start injector would cause.
Why is your 1993 4Runner hard to start in cold weather?
Check your battery first.. If it is fine, you might need to replace your cold start injector timing switch. Fairly expensive, but should work.
When cold you have to pump accelerator many times before it starts What could be the problem?
pumping probably isn't helping if the truck has fuel injection. extended cold crank times are often caused by a bad cold start injector or the control for the injector. also if there is no fuel pressure (i.e. a fuel pressure regulator that is leaking back into the tank as the car sits), it will take awhile to start.
