Blown Fuses



If the previous solution does not resolve the issue, you might be dealing with blown relays 9, 26, and 27. Begin by checking fuse 9. Although its location may vary between generations, it could be in the interior fuse box or the engine bay.

To simplify the search, you are looking for the fuse designated for the PCM/TCM and fuel pump relay. Furthermore, fuses 26 and 27 in the engine bay fuse box could also be culprits.

Accessing these fuses is relatively straightforward. Fuse 26 has a rating of 10 A, while fuse 27 is rated at 5A. However, it is always advisable to inspect all the fuses when time allows and ensure they are all securely seated.

Disconnect the Battery



For some individuals, disconnecting the battery seemed to resolve the issue. This would not solve the issue permanently, but it may offer a temporary cure.

Even though the exact reason why it worked is not quite obvious, make sure to unplug the negative terminal of the battery and keep it detached for at least 10 minutes when disconnecting it.

The factory terminal clamp bolt is typically 8 millimeters or 5/16 inches, but another instrument that works similarly can be used, like pliers. Examining the key is the next step to take if the error notice still appears after using this technique.

Replace the Key



If none of the previously mentioned solutions prove effective, though it is unlikely they would not, the key becomes the last possible culprit. Before purchasing a new key, if you have a spare, it is advisable to test it, as spare keys often resolve the issue.

If the spare key successfully starts the car, consider replacing the battery in the original key or having it inspected by a dealer. However, if you lack a spare key, a visit to a dealership becomes necessary.

Before requesting a new key, have them conduct a thorough inspection of your vehicle. A new key from a dealership typically costs around $280.

As an alternative, contacting a local locksmith is an option, as they often create such keys. In this case, the key may range between $80 and $180. It is essential to clarify with the locksmith whether any features will be missing so you fully understand the key's capabilities.

FAQ

How do you reset the anti-theft system on a Ford Ranger?

Begin by inserting the key into the driver's door lock and turning it slightly counterclockwise, without fully unlocking the doors. Maintain this position for approximately 50 seconds.

Next, turn the key clockwise but not to the point of locking the doors, and again hold it in this position for 50 seconds. Finally, unlock the vehicle and start the engine.

How do I disarm my Ford anti-theft system?

Disarming your Ford anti-theft system can be done in three ways. The first method is to use a remote key to unlock the doors or trunk.

The second option is to start the engine if the doors are already unlocked. Lastly, you can disarm the system by physically unlocking the doors with a key, but remember to start the engine within 12 seconds afterward.

Can a sensor keep your car from starting?

It is true that your car may include a number of sensors, including fuel pressure, throttle position, crankshaft, camshaft position, and brake pedal. It is crucial to remember that none of these sensors is in charge of bringing up the "starting system fault" notification.
