Could be a number of things. First, use a long wooden or metal rod, maybe an extra long screwdriver, and place it against the injector with the engine running. You should be able to hear a clicking noise telling you that the injector is trying to work. If you hear the clicking, the check your plugs and wires. If you don't, recheck the injector. If you do not hear the clicking, pull the wiring cap off the injector and check with a test meter for voltage while cranking or running the engine. I have had several that had broken or burned wires in the injector circuit or loose or bad fitting wiring caps, especially prior to 1989. Try switching #1 or #2 wire cap onto the #3 injector and see what happens. If #3 starts firing and #1 stops firing, the problem is in the wiring harness. By the way, all of the injectors on a 22re pulse at the same time on both exhaust and compression stroke so switching them won't cause any problems or damage. Even though they all inject at the same time, they are on 2 circuits. #1 and #3 on one circuit and #2 and #4 on the other. Hope this helps
Either the "O" rings are bad where the injectors go into the cylinder head or the electrical connector on the injector is leaking.
the injector may be worn off, try replacing the flooded cylinder injector
Typically that is caused by a little buildup of deposits around the inside of the injector tips. Sometimes you can put a can of injector cleaner through the system and clean out the deposits. Use the injector cleaner as described on the can. It may take a couple applications to clean the injectors. Sometimes that doesn't work and you'll need to replace the faulty injectors. Good luck.
A fuel injector pulse is the product of an electrical charge controlled by the ecm to briefly open an injector. If the engine is throttle body injected, you would find the injectors in the throttle body.
I had two leaky injectors in my '96. I tried replacing the O rings and it helped, but didn't solve the problem. I ended up replacing the injectors. That was about a year ago and the injectors were about $75 each at Auto Zone. For what it's worth, my mechanic helped me do this job. When she put the new injectors into the seats, she first coated them with some Vasaline lookin' stuff. I'm guessing that the lube helped to get the injectors in smoothly and maybe sealed the injector to seat surface. FriPilot
This engine will have seven injectors. 6 are the running injectors and there is a "Cold Start" injector.
The electrical fuel injector connectors (2 of them) are located on top of the fuel injectors which are located on top of the throttle body. Assuming this is a 4.3L engine.
It would be very unlikely. Fuel injectors give very little problems.
You can try using a fuel injector cleaner that you add to the fuel tank but that's about all you can do at home other than replacing them.
Firstly make the engine bay safe by removing the battery. Remove the engine cover by undoing the 4 retaining quarter turn caps. Crack off the highpressure pipes that go from the common rail to the injectors, make sure you do this gently and with the correct size spanner or crowfoot socket. Undo the pipes fully from the common rail and the injectors. unplug the injector from the harness (the small electrical connector on the top of each injector) with the pies out of the way you can now access the 13mm nut that holds the injector support bar. Then the injectors can be lifted out, sometimes they need a little persuasion, but be gentle. Also make sure once the injectors have been removed the copper ring on the bottom of each injector is replaced and is totally clean before refitting.
which injector you looking for? there are 8 injectors in that engine
A malfunctioning fuel injector pump will cause the injectors to not fire properly. The fuel injector pump will need to be replaced.
Depends on the car... If you can see the injectors, you'll need to disconnect the wiring harnesses from the injectors... (there is also usually a boot over the injector). You then need to disconnect the injector from the fuel rail. (careful not to strip the little fitting). You can then use a wrench or injector socket to remove the injector. Make sure you replace the gaskets and seals when installing the new injectors. (might need teflon tape around the pipe fitting where the injector feeds from the fuel rail).
Yes, replacing fuel injectors on a 4.6 L Ford F150 is pretty simple and easy. As long as the person has the correct tools for the job and is not in a hurry, then it remains easy.
It has 6 injector 1 Injector per cylinder
Fuel injectors run on electricity, and an electrical impulse to fire. When the charge is gone, so to is the ability for a fuel injector to move fuel to the engine block. You are getting fuel to the fuel injector, but not the engine. Check the voltage going to the fuel injectors. -no voltage, or not enough --short circuit in fuel electrical system. --replace the ecu (check the manual or call the dealership) -good voltage to injectors, replace the fuel injectors. Go here to get new ones shipped out before you remove the old ones. http://www.fuelinjectorwhse.com
Fuel injectors do go bad....just like any other part of the engine. Some shops recommend replacing them during a tune up. Others at least recommend a good cleaning. Running good quality gasoline and a good injector cleaner a couple times a year will do wonders for them lasting longer. There is also the electrical portion of the injector which goes bad and there's not much that can be done to prevent that. I've seen them go bad in less than 100k miles....and then there's my Expedition that still has the original injectors with 208k.
p2146 = Fuel Injector Group A Supply Voltage Circ/Open The circuits or injectors for cylinders 1, 2, or 3 have an electrical problem.
Yes, it's possible. I had two leaky injectors in my '96 Sunfire. Replaced the O rings to no avail. I ended up replacing the two injectors even though inspection showed no damage. The fuel leak was fixed.
the problem is that injectors are forced into head . since head is aluminum and injector is steel after few years they become stucked together as they are one piece . you may expect that at least one injector will be broken during extraction . if you have spare/new injectors best way is to unscrew upper part of injector and chip the rest out with adequate tool . also if injectors are succesfuly removed there is problem with sealing new ones because during removal head will be almost certanly damaged . strongly recomending replacing whole head with injectors . used one in good condition is much cheaper than set of new injectors and head repair . This is absolute nonsense, make a injector puller sliding hammer type and loosen holding clamp and wiring then pull hard upwards and the injectors will come out.
Where is the fuel injectors
Switch the electrical connections between the two injectors and see if the same one is still bad or if the problem switched to the other one. If the same one is bad, you have a bad injector.
You might check the controller for the fuel injectors sometimes they can go hey wire you can use a multimeter and check it to see if it's firing in the correct order and if it's not you might need to replace it. Give that a try also check for shorts in the wires from the injector connector from the injector all the way back to the controller. Hope that helps. :)
to reset an injector , is a specialist job if injector is faulty, it needs replacing
This problem could be due to many things, but it's probably time for a tune-up. I'd start by replacing the spark plugs and the air cleaner. Also, if you are smelling raw gas, you might have a cracked fuel injector, or bad injector O rings. I learned this from experience on my "96. I replaced the O rings on two leaking injectors, as there were no visible cracks in the injectors. It helped but didn't solve the problem. Replacing the injectors was the answer. For what it's worth, my "96, when it's running well, gets about 33 MPG. FriPilot
