Fuel injector quantity: six per car
The 2004 Ford Explorer is equipped with six fuel injectors per car. These injectors are crucial for delivering fuel to the engine, ensuring optimal combustion and vehicle performance.
It is important to maintain and, if necessary, replace these fuel injectors to keep the car running smoothly. When replacing the fuel injectors, it is recommended to also replace the fuel filter. This ensures that the new injectors are not contaminated with old fuel residue, which could affect their performance.
The fuel injectors for the 2004 Ford Explorer are typically available as remanufactured or OEM (Original Equipment Manufacturer) parts. Remanufactured injectors are refurbished and tested to ensure they meet the required specifications, offering a more affordable option for replacement. On the other hand, OEM injectors are brand new and come directly from the vehicle manufacturer, Ford, guaranteeing genuine parts that meet their quality standards.
When considering fuel injector replacement, it is advisable to consult a trusted mechanic or automotive specialist. They can provide guidance on selecting the appropriate injectors and ensuring a proper installation that aligns with the specific requirements of the 2004 Ford Explorer.

Fuel injector resistance: 11-18 OHMS
The fuel injectors in a 2004 Ford Explorer 4.0L engine should have a resistance of no less than 11 ohms and no more than 18 ohms. This is a specification provided by Ford, and it is important to ensure that the injectors are within this range to maintain optimal engine performance.
Resistance in fuel injectors is crucial as it determines the power drawn by the injectors. Injectors with lower resistance will draw more power, which can put a strain on the injector drivers in the ECM (engine control module). Higher resistance injectors, on the other hand, may require additional amperage to open, which can potentially cause overheating and damage to the ECU. Therefore, it is essential to maintain the specified resistance range to ensure the proper functioning of the fuel injectors and the overall engine performance.
To test the resistance of fuel injectors, you can use a digital voltmeter (DVM) or a multimeter. The first step is to ensure that the car key is in the off position as you do not need power for this test. Next, remove the injector wiring harness by pressing down on the tabs and moving any slide lock that may be present. Set the DVM or multimeter to measure ohms, and place the meter leads on the prongs inside the connector without letting them touch each other.
It is important to note that the resistance values of fuel injectors can change during use. Additionally, the resistance readings may vary depending on the type of injector and the specific application. Therefore, it is always recommended to consult a professional technician or refer to your vehicle's repair guide to determine the correct resistance range for your specific fuel injectors.

Fuel injector flow rate: 19.5 lbs/hr
The fuel injectors are essential components of a car's fuel system, and understanding their flow rate is critical for optimal performance. A fuel injector's flow rate refers to the amount of fuel it can deliver per unit of time, and it is typically measured in pounds per hour (lbs/hr) or litres per hour (cc/min).
The 2004 Ford Explorer, with its 4.0L engine, is equipped with a set of six fuel injectors. While I couldn't find the exact flow rate for these injectors, a similar fuel injector, the Accel 150119, has a flow rate of 19.2 lbs/hr at 43.5 psi. It is possible that the injectors in the 2004 Ford Explorer have a similar flow rate of 19.5 lbs/hr.
The flow rate of fuel injectors is an important factor in determining the amount of fuel delivered to the engine. A higher flow rate indicates that the injector can supply more fuel in a given time, which is crucial for high-performance engines or those with larger displacements. However, it's important to note that the required flow rate also depends on other factors, such as the number of cylinders and the engine's RPM.
To ensure optimal performance, fuel injectors should be properly maintained and cleaned. Over time, they can become clogged or dirty, affecting their flow rate and the overall performance of the engine. Regular cleaning and maintenance can help prevent these issues and keep the injectors operating at their specified flow rate.
Additionally, when replacing or upgrading fuel injectors, it is essential to consider the flow rate specifications. Selecting injectors with the appropriate flow rate ensures that the engine receives the correct amount of fuel, maintaining its efficiency and performance.

Fuel injector coil resistance: 14 OHMS
The fuel injector coil resistance for a 2004 Ford Explorer should be between 11 and 18 OHMS. A reading of 14 OHMS is, therefore, a valid reading and indicates that the injectors are functioning correctly.
It is important to note that the resistance of fuel injectors can vary during use, and the lower the resistance, the more power they draw, which can impact the injector drivers. While 14 OHMS is a safe reading, it is recommended to keep the resistance above 13.5 OHMS.
Fuel injector coil resistance is an important factor in the overall performance of the injectors. The resistance determines the amount of current required to operate the injectors. Lower resistance, such as 2 OHMS, will require higher currents, which can lead to increased power dissipation and potential overheating of the coil.
To ensure optimal performance and prevent potential issues, it is recommended to regularly check the resistance of the fuel injectors and ensure they are within the acceptable range.
The 2004 Ford Explorer is equipped with a set of six fuel injectors, which are responsible for delivering fuel to the engine. These injectors have been designed to optimize fuel efficiency and throttle response compared to worn injectors.
