Cleaning the fuel injectors on the Ford Ranger is a straightforward process that involves simple steps and tools. The Ranger is identical to the Mazda B Series, so the procedures apply to both. The fuel system is nether high pressure to vaporize properly on signal. It is important to release this force per unit area prior to doing any other piece of work.

Pace 1

Relieve the fuel pressure by disconnecting the power to the fuel pump switch. It is located in the passenger compartment behind the glove box in 1994 and earlier models. Afterwards models placed the switch backside the rider side kick panel. B-Series trucks placed the switch nether the carpeting on the passenger side of the manual hump. Remove the plug to disable the inertia switch. Turn the key to run the starter motor for 15 to 20 seconds in club to relieve the pressure. Exist sure to plug the connector in when you finish.

Step 2

Open up the hood. Disconnect the air cleaner and hoses by removing their retaining screws and clamps. Most models have a 2-slice intake manifold to feed air into the engine. The upper portion, consisting of cast metal tubes under the air cleaner, must exist removed in all models except mail service-2001 four-cylinder models. Label and disconnect all electrical connections and vacuum lines attached to the manifold, and use a ratchet and socket to remove the bolts securing information technology to the lower half. Remove the clamps connecting the fuel lines to each terminate of the metallic tubes -- the fuel track -- running forth the top of each cylinder caput. Fuel is probable to spill, so be prepared with several rags to clean up the mess before proceeding.

Footstep three

Label and disconnect all electrical connectors attached to the injectors located nether the fuel track. Unbolt the fuel rails and gently rock them free. The injectors are plugged into the fuel rails and may come up out with the rail. If they exercise not, carefully work any remaining injectors costless with your fingers from the lower intake manifold or the track. Be sure to check for whatsoever "O" rings left behind and remove them.

Pace 4

Remove the "O" rings -- two per injector -- and the filter from the bottom of the injector. Put the injector cleaning solution in the bucket and soak the injectors. The more dirt and grime on the injectors, the longer they should soak. If necessary set up a clean batch of solvent and echo the soaking process.

Remove the injectors from the solution and apply the compressed air to accident any residue out of the nozzle. Inspect each injector for cracks or signs of excessive wear and replace if necessary.
