Where is the fuel injector located on a jeep?
Fuel injector is mounted in throttle body so that fuel is injected into incoming airflow. When injector solenoid is energized, armature and plunger move upward against spring. Check ball above injector nozzle moves off seat and opens small orifice at end of injector.

What causes fuel injectors in Jeep Cherokee to go bad?
There are two main ways that your injectors can go bad. The first is for them to become clogged, dirty, or unresponsive. When this happens not enough fuel enters into your Cherokee’s combustion chamber. The other way is if the injectors are leaking.
How does the YJ fuel injection kit work?
A mechanical Jeep YJ fuel injection kit functions by responding to air pressure. The faster your Jeep goes, the more fuel it needs. As more air passes over the injection kit, it releases the exact amount of fuel and air that the engine needs in order to respond correctly.
How does fuel injection work on a jeep?
Fuel injection delivers the precise amount of air and fuel to the engine to improve your Jeep’s performance. A mechanical Jeep YJ fuel injection kit functions by responding to air pressure. The faster your Jeep goes, the more fuel it needs.

Where is the idle switch on a jeep?
TPS is mounted on throttle body assembly. WOT switch provides an input signal to ECU when engine is at wide open throttle. The ECU enriches air/fuel mixture. The WOT switch is located on the side of throttle body. Idle switch is integral with ISA motor and provides voltage signal to ECU.
Is the fuel regulator part of the throttle body?
Fuel pressure regulator is integral part of throttle body. Pressure regulator has a spring chamber that is vented to same pressure as tip of injector. Because differential pressure between injector nozzle and spring chamber is same, only the length of time that injector is energized controls volume of fuel injected.

What causes fuel injector to leak and cause hard starting?
Leaking fuel injector can be cause of hard starting. This is because the fuel rail pressure has dropped and fuel has leaked into the manifold and causes the spark plugs to become flooded. Both top feed and side fuel injectors make use of O-rings to seal between the fuel injector and fuel rail.
Can a fuel injector be tested under pressure?
Fuel injector leak testing should be done under operating pressure. The average DIY fuel injector cleaning project and most automotive repair shops does not have the proper diagnostic equipment or the ability to test leaking injectors or clean them properly.
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.
