No, no, don't do that! It's like lighting a cigarette with a blowtorch, a bit much. I'm pretty sure there are some videos on youtube showing homemade injector cleaning set-ups.

You didn't give any information what your injector is in, you know all manufacturers don't do everything exactly alike. Year, make, model, and engine size is how we can make a reasonable response. But FWIW, injectors are usually located in a "fuel rail" or a long pipe, on top of the engine, so that the injector nozzles can be directed into holes that are very near the intake ports of each cylinder. You know, where the intake valve opens into the combustion chamber, at the top of the cylinder, so that air or the air/fuel mixture can be drawn into the cylinder. This is where you would want the injector to spray into: the onrushing air going into the cylinder through the now-open intake valve, drawn in by the piston moving down. The intake ports would be in the intake manifold. In a V-block engine, the intake is in the valley between the two banks of the engine. In a straight 4 or straight 6 engine, the intake manifold is mounted to the side of the cylinder head. Some manufacturers may situate the injectors to spray directly into the top of the combustion chambers, but even those share a common rail to keep gas under high pressure on the injectors. Another type of injection system is called Throttle Body Injection, but that's kind of old style, now.

As to removal procedures, check youtube for your particular vehicle, or better yet, consult a Haynes or Chilton repair manual. Then you have a step-by-step procedure. If you follow it, you can't go wrong, almost never. But never say never.

Make and model would help, the injector should be after the throttle body on the inlet. A welding tip will not even go close to repairing it.

What is the average cost to clean fuel line and injectors on a1990 jaguar xj6 ?


Clean How?

On a vehicle that old, you remove the injectors
& mail them to a place that ultrasonically cleans them

That is about $45.00 each

There is no fuel line cleaning

You could have them cleaned on the car with the
injector cleaner that is put in a container & pressurized
to at or 5 lbs above rail pressure,the pump fuse removed
& run off that mixture

Don't know what that costs. Say $100.00 or less

How to remove bad gas from 2001 impala


Bad gas can cause several concerns depending on what's in it. If it's only a liquid type bad gas then it can be purged. If it has debris it's another story. With a liquid only concern, a scan tool can be used to turn on the fuel pump and pump out the fuel by removing the fuel line at the injector rail or fuel filter. The fuel is under pressure so please use safety glasses and relieve the pressure. If the fuel had debris in it, the tank should be removed and completely cleaned, the lines should be purged, the filter replaced and an injector flush performed which requires a special tool. Fill the tank with fresh gas after repairs and monitor engine performance. The fuel injectors have tiny orifices that spray the fuel and are subject to clogging. If there's any reason you can't give four thumbs up, please request more information. Thanks and good luck!

I need to replace the #2 fuel injector. Is this something a layman such as I can accomplish?


You could do it, but remember gasoline is flammable and volatile and can be hazardous to work with: REMOVAL AND INSTALLATION 1.9L Engines
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Properly relieve the fuel system pressure.
  3. Remove or disconnect the following:
    • Negative battery cable

I needto know how to replace a Crankshaft postion sensor A circuit


      • The sensor is mounted in a fixed position in the engine block. The tip of the sensor protrudes into the crankcase at a distance of 0.05 plus or minus 0.02 inch from the crankshaft.
      • A crankshaft adjusting tool may be used to check these rings
      place the tool on the pulley extension surface and rotate the tool around the pulley.
    • If any blade touches the tool, replace the pulley.
  • Inspect the trigger wheel behind the crankshaft pulley and the sensor for damage.
  • If the engine misfires all the time or on acceleration only, test the following components:
    • Engine compression.
    • Spark plugs.
    • Spark plug wires.
    • Ignition coils test for firing voltage with a test spark plug.
    • Crankshaft sensor.
    • Fuel injectors on multiport and sequential fuel injection systems. To remove the crank sensor
  • Disconnect the wiring harness.
  • Unbolt the sensor mounting bolt.
If the crankshaft timing sensor or the camshaft reference sensor is removed, follow this procedure when the sensor is replaced:
  • Thoroughly clean the sensor tip and install a new spacer on the sensor tip. New sensors should be supplied with the spacer installed.

  • Install the sensor until the spacer lightly touches the sensor ring, and tighten the sensor mounting bolt 105 in.lb.

How do i put a fuel injector in


Try cleaning the injectors... http://fordfuelinjection.com/?p=82 will give a few ideas on how to do a cleaning. Other than a cleaning, you need to be sure that the injectors are receiving the signal to operate, this is tested with a noid light.
Other than that, if you still want to replace the injectors, first relieve fuel system pressure by: 1) Look in the trunk for the fuel pump shut off switch. Turn it off.
2) start the car and let it run and stall out (should not take long)
3) Now the fuel system is depressurized
Now you can go in and begin the removal. 1) remove air intake plenum (on 5.0 it is the metal swept to one side looking thing on top of the engine)
2) remove the fuel rail assembly (you will need fuel line couple tools to make this happen, otherwise trying to improvise one will damage the coupling and give you a fuel leak)
3) Detach the electrical connectors from each injector (be careful and gentile like)
4) Grip the entire fuel injector with one hand and pull while gently rocking it back and forth. Don't yank, use a stern wiggle
5) First check once you get the injector out will be the O-rings, look for deterioration cracks or other signs of boo. (In general, replacing the O-rings is recommended once you have the injector removed)
6) Inspect the injector for signs of wear, and deterioration or breakage (if broken, you may want to investigate your manifold for the offending pieces)
Reinstall: 1) Lubricate the O-rings (use light oil only...no grease/silicone, they will clog the injector)
2) Lightly twist the injectors into place.
3) replace the previously removed parts
Tips: Recommend using a digital camera before and during your procedure. That way you have a photo reference of what things looked like before they were disassembled as well as what the progress was like, and you can refer to your own photo guide as you work.

1993 ford escort wagon,no electric to injectors


The fuel delivery system uses an electric fuel pump to provide high-pressure fuel to the fuel injectors. The fuel pump is located at the rear of the vehicle, mounted in the fuel tank. It can be accessed by removing the rear seat.

The fuel tubes leading from the fuel tank to the engine are under pressure during vehicle operation. When the engine is turned OFF, the fuel in the fuel tubes remains pressurized for long periods of time to provide quick start-ups. Fuel not used by the fuel injectors during operation is routed back to the fuel tank through the fuel return tube.

The fuel handling components are protected by three fuel filters. A replaceable in-line fuel filter is located inside the engine compartment between the fuel tank and fuel injection supply manifold. A serviceable filter screen is located inside the fuel tank at the fuel pump inlet. A non-serviceable filter screen is incorporated into each fuel injector.


I can get you trouble shooting tips if you want them.
