Where is fuel shut off solenoid on a CASE 1845C?
in injector pump
Where is injector solenoid on 1993 Ford F-250?
The 1993 Ford F2 50 pickup truck injector solenoid is attached to the injector fuel pump. The injector solenoid should be labeled as such.
What is the function of electric solenoid in the carburetor of caprice classic 1988 year model?
The electric solenoid in the Quadrajet carburetor is called the Mixture Control solenoid and, in short, it meters (controls) the air/fuel ratio. This device helps to reduce emissions and improve fuel economy. In more detail, the Mixture Control (M/C) solenoid meters the amount of fuel that flows through the idle main metering circuits in the carburetor. The ECM (Electric Control Module) is the car's computer, and it tells the M/C solenoid how much fuel to meter. The ECM energizes and de-energizes the solenoid ten times per second and may keep it energized longer than it is de-energized. When the solenoid is energized longer than it is de-energized it provides a leaner mixture, and in effect it improves fuel economy. When more fuel is needed it is de-energized longer or completely de-energized. So, imagine that you are at a stop light and your car is idling. The ECM should energize the solenoid longer than it is de-energized, and less fuel is provided which leans the air/fuel mixture. This can help lower emissions a bit and improve fuel economy. When the light is green and you press the gas pedal with a moderate amount of force or to the max, the M/C solenoid will be de-energized longer than it is energized (or completely de-energized) which enriches the air/fuel mixture and provides more fuel. A faulty M/C solenoid will likely be in the de-energized position and it may reduce fuel economy and increase emissions; if the solenoid is somehow stuck in the energized position, engine performance may decrease. In this position it may also be difficult to start the car and it may stall at idle.
Where is the fuel injection needle located?
Well, a fuel injector isn't a needle, it's a solenoid valve. They are located on the intake manifold.
Why would the RPM gauge be all jumpy on a 1995 GMC Sonoma?
I had a similar problem. Turned out to be a bad solenoid on the fuel injector. Required the replacement of the entire fuel injector. After that, the problem was solved.
On a 92 Pontiac grand prix with a 3 4 there is fuel pressure of 40 lbs and it will fire if fuel is sprayed into the intake but not on its own Any ideas what else it could be?
I've seen this before on GM fuel injected cars.. It could be that your fuel injector solenoid circuit has gone onto shut down due to a shorted, or very low resistance injector solenoid. Check your injector solenoids with an ohm-meter. They should be around 16 ohms..
How fuel injector is operated?
A fuel injector is pretty much like an electric solenoid. The injector is therefore an electrical and mechanical component. It opens and closes a plunger which is pulsed in the injector by the on board computer. The computer uses all the other sensors on the vehicle to calculate how long or how many pulses needed to keep the fuel injector open. Fuel is driven to the injector or injectors by an electric pump which also is regulated by pressure. The injector is closed before compression of the engine or is opened on the down stroke of the cycle. In other words; when the injector has electricity going to it, then it opens. Without electricity it naturally closes.
What does code 25 mean on 1995 Aspire air bag light?
code 25 -refers to a short or open circuit between the solenoid valve to ECM.possible broken fuel pressure regulator or short circuit from solenoid valve to fuel injector main relay. check selenoid valve.(fuel pressure regulator control solenoid)
How do you bleed your fuel injectors 1994 Aucra Integra 1.8 liter?
You don't. You can't. And I have never heard of bleeding an injector. Its just a solenoid that opens and closes.
How do you change a fuel injector in a 1987 Nissan maxima?
Where is the fuel injector located?
What makes a fuel injector fire?
The fuel injector provides the fuel. The spark plug provides the fire.
Does the ford explorer 4.0 equipped with a carburetor or fuel injector?
It is equipped with a fuel injector.
