Why is my throttle body injection not working?
When this automotive part is not working correctly, or its electronic sensors begin firing off readings to the onboard diagnostic computer showing problems, it can create car problems.
Why is my fuel injection system plugged in?
The electric fuel pump installed for a fuel injection system will draw considerable more volume of fuel from your tank than your old system did. If there are any contaminants in the tank this many times will plug up or greatly restrict the flow of fuel to the system causing many issues. Step by Step Troubleshooting guide.
What should fuel pressure be on a TBI fuel injection system?
Fuel Pressure is critical to the operation of a fuel injection system. Always check to insure that you have the proper fuel pressure. Fuel pressure should be a constant 10 – 15 PSI on a TBI fuel injection system and is typically around 12 – 13 psi. Higher pressure than 15 psi indicates that there is an issue with the installation.
What happens if the fuel pressure regulator fails?
The fuel pressure regulator controls the fuel pressure in the fuel rail. If there is something wrong with the fuel pressure regulator, it can create too low or too high fuel pressure in the rail. It is not very common that this part fails, but it can happen.
When do you assume there is enough pressure in the injectors?
If the engine runs, they assume the injectors are getting adequate fuel pressure. If the engine cranks but won’t start, and they depress the service valve on the fuel rail and some fuel squirts out, they assume the injectors have pressure. They do, but the question remains, “How much pressure?”

How does a return style fuel injector system work?
Return style systems hold a big advantage in that with a vacuum/boost referenced fuel pressure regulator, the system can maintain a CONSTANT effective fuel pressure, which can extend the range of fuel injectors and help them function at lower fuel demands as well.

How does the throttle body work in a car?
The throttle body in a car provides the control of air and fuel injection so that the system runs efficiently and does not backflow. When this automotive part is not working correctly, or its electronic sensors begin firing off readings to the onboard diagnostic computer showing problems, it can create car problems.
Can a malfunctioning throttle body cause check engine light to come on?
Not only does a malfunctioning throttle body have the capability to cause the check engine light to come on, it can also cause other sensors to overcompensate, causing other problems elsewhere. Typical related issues will include the oxygen sensor and the mass air flow sensor.
What to do if your throttle body is stuck?
Check that the throttle flap is not stuck open. Use a socket wrench and crescent wrench to loosen the bolts holding the throttle body to the engine block. Pull the unit off and disconnect the electronic sensor from the car wiring.
Why is my throttle body not working properly?
The issue could also be an incorrectly adjusted throttle stop. This is a component that acts as a gate-keeper and establishes a minimum or maximum position for a throttle body plate to be opened or closed. A maladjusted stop wouldn’t allow in the correct amounts of air and fuel.
What does the throttle body plate do on a car?
This is a component that acts as a gate-keeper and establishes a minimum or maximum position for a throttle body plate to be opened or closed. A maladjusted stop wouldn’t allow in the correct amounts of air and fuel.
How does the throttle position sensor work on a car?
As you press down on the pedal, the throttle position sensor receives a signal relative to where your foot is, ranging from all the way up (zero acceleration) to all the way down (full acceleration). This sensor relays the information to the car’s main computer — giving it constant updates as to the position of the throttle.
Fuel Pressure is critical to the operation of a fuel injection system. Always check to insure that you have the proper fuel pressure. Fuel pressure should be a constant 10 – 15 PSI on a TBI fuel injection system and is typically around 12 – 13 psi. Higher pressure than 15 psi indicates that there is an issue with the installation.
What does a throttle body scan tell you?
You can expect the scan to indicate problems with your fuel injection system and specifically throttle body component if the problem is in throttle. Symptoms of car trouble are not to be ignored, especially if you don’t want to spend any more money than you actually have to.
What are the symptoms of a bad fuel injector?
Fuel injector symptoms for bad, faulty, dirty, clogged, or leaking injectors are : Starting issues Poor idle Failed emissions Poor Performance Engine does not reach full RPM Increased fuel consumption Rough engine performance Surging and bucking under various throttle loads Smoke from the tail pipe
What does it mean when your throttle body is dirty?
The throttle body is a large valve where fresh air from the air filter enters the engine, and it can easily become dirty. When everything is working properly, your car’s engine gets a perfect ratio of air and fuel which makes the car run smoothly and gives an optimum performance.
What should I do if my throttle body is bad?
As a part of your regular service intervals, include the air induction service and fuel injection flush to clean out any carbon deposits and dirt. You will need to have the check engine light shut off by a qualified mechanic.

How can I keep my fuel injector in good health?
Another great way to keep injectors in good health is; to regularly add a fuel injector cleaner to to your fuel tank. Many manufacturers claim that these cleaners, will give your car extra power or increased mpg. They probably won’t, or make much difference, to a car that is running properly.
What does the throttle body do in a car?
In today’s modern fuel injected cars, the throttle body is a critical piece of the air intake system that controls the amount of air flowing into the engine. The amount of air allowed in is a function of how far the driver presses the accelerator pedal to the floor.
