This will sound a bit silly and obvious but have you tried a new battery in the transponder key? Sometimes the fix is that easy.
Have you had the vehicle plugged into an OBD scanner or a diagnostic system? Dashboard codes are commonly a bit vague about what the issue is. A Code 24 simply comes up as 'an Immobiliser issue' and thats all you get. The OBD scan will also tell you if there are any other issues with any of the other sensors on the engine.
Comment below with any trouble codes you get and I'll try to help you more.
If you've replaced the Mass Air Flow (MAF) sensor three times and it still keeps coming up as bad, there could be a few other issues at play:
1. **Wiring or Connector Problems**: Check the wiring harness and connector for any signs of damage or corrosion. Poor connections can cause erroneous readings and trigger the MAF sensor code.
2. **Air Intake System**: Inspect the air intake system for leaks, cracks, or loose connections. Any unmetered air entering the engine can disrupt the MAF sensor's readings.
3. **Vacuum Leaks**: Vacuum leaks in the engine can affect the MAF sensor's performance. Inspect vacuum hoses and connections for leaks or damage.
4. **Faulty PCM (Powertrain Control Module)**: In rare cases, the issue could be with the vehicle's computer. A malfunctioning PCM may not be interpreting the MAF sensor data correctly.
5. **Other Sensor Issues**: Problems with other sensors such as the oxygen sensor or throttle position sensor can sometimes trigger MAF sensor-related codes.
Consider having a professional diagnostic done if you're unable to identify the issue yourself, as they can use specialized tools to pinpoint the exact cause of the problem.
Remove the plug completely and check the internal pin and socket contacts. Spray the outside of the male socket with WD40 and offer the two connectors squarely together until it locks.

The pump is located underneath the car, a short distance away from the fuel tank. It is mounted above a protective plate and looks similar to a fuel filter canister. You will need to clamp the fuel supply pipe BEFORE you remove the pump. Remember this is Petrol your working with! You will most likely have to remove the bracket plate it mounted on to get the pump out.
Radio Volume and Sound Issues:
The fact that the radio is on but the volume knob doesn't respond and there's no sound from any source suggests a problem with the Digital Signal Processing (DSP) module. This module is responsible for audio processing and distribution.
The C1001:01-68 code points to a fault in the rear camera, while the B1215:00-28 code indicates an issue with the Accessory Protocol Interface Module (APIM).
Since the HVAC and GPS are functioning correctly, it's likely that the APIM itself is not operating as expected.
To address the sound issue, consider replacing the DSP module. Here are the steps:
Remove the subwoofer (it's held in place by three bolts).
Install the new DSP module.
Use FORScan to program the replacement module.
Backup Camera Issue:
The backup camera has also stopped working, displaying a message to contact the dealership.
You might want to try the following common fixes:
Master Reset via Software in SYNC 2: This can sometimes resolve camera issues.
Forced Reset via Disconnecting the Battery: Disconnect the vehicle battery for a few minutes and then reconnect it. This can reset various modules, including the camera.
Replacing the Camera Itself: If the camera remains unresponsive, consider replacing it
Gates 352714 Power Steering Return Line Hose Assembly for 2007 Ford Expedition 5.4L V8 Gas SOHC.
I found this number, look online eBay or amazon or go to local parts store. Be sure to replacement power steering fluid that i compatible to your car..
personally i would use peratx, it will help hold gasket in place on water pump. Place small amount on backside of gasket that mates to block. I like to place new pump on a piece of cardboard and trance outline and mark hole. Cut holes with a knife. Place bolts in the template as you take them out. this will ensure that bolts do not get mixed up.
The proper spark plug gap for your 1998 Ford Ranger 2.5L with 8 plugs depends on the specific spark plugs you're using. Here are some recommended gap values:
Champion RC8PCY: Gap of 0.8mm.
NGK PFR6B-II: Gap of 1.1mm.
Throttle Body Relearn:
After replacing the throttle body, it's crucial to perform a relearn procedure to ensure proper communication between the new components and the car's computer.
Here are some methods to reset the throttle position sensor (TPS):
OBD2 Scanner:
Use an OBD2 scanner compatible with your car model.
Look for the throttle sensor reset feature in the scanner.
Follow the scanner's instructions to reset and calibrate the TPS.
Accelerator Pedal Method:
Turn the ignition to the ON position (without starting the engine).
Push the accelerator pedal down fully for about 20 seconds.
Release the pedal slowly and turn off the car.
Start the engine normally and check if the situation improves.
Fuse Removal:
Locate the fuse box (details in the owner's manual).
Remove the fuse related to the throttle body (leave it out for about 10 minutes).
Reinsert the fuse.
The throttle body sensor should reset.
Driving the Vehicle:
Drive the car on the highway at speeds over 40 mph.
Accelerate and decelerate slightly.
Repeat this process to allow the sensor to reset.
Additionally, there's a helpful YouTube video that specifically describes the relearn procedures after replacing the throttle body and the throttle position sensor (TPS) .
Check for Other Issues:
Ensure that the ignition coils, spark plugs, and front oxygen sensors are in good condition.
