If you are only getting fuel out of two lines, then the injection pump is probably bad.
If it is just one injector, it is a bad injector or a problem in the wiring harness or connector for that injector. If it is all of the injectors, it could be a fuse, the entire injector harness, a broken loose or unplugged connector on the injector harness, or the fuel pump or fuel pressure regulator.
you must change/rebuild all four of the to insure even fuel spray out of the injectors. first remove the top half of the EfI system, once the top half is gone, remove the fuel line from injector rail, disconnect the plugs from injectors. remove injector rail and all four injectors as one. the reverse for installing the. be very careful with the new injectors when installing as they are fragile little thing. never reuse the rubber o rings on the injectors. they are usually the culprit of injector leaks or air getting in.
Check the camshaft sensor. If the sensor is bad or not getting power, then the engine will not fire and the injector will not get a signal.
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
Sounds like the injectors are failing by staying open too long. Probably time for new injectors. Impossible to test without an inline injector tester. Hope this helps.
Are you sure you are changing injector #7? Should be the injector closest to the firewall on the drivers side. If you are changing the correct injector, and the code remains, the problem is with the wiring from the injector to the pcm (computer) or the computer itself. You can check for correct battery voltage at the injector with a volt/ohm meter (how does the connector look at the injector?). This year of Durango/Dakota had trouble with computers too, although I have not heard of specific injector trouble being caused by the computer. Most likely a wiring problem. It may even be the TPS
Most injectors should show battery voltage IE approx 13V. Where to look if not getting voltage. Immobiliser. Injector relay. Wiring harness. Crankshaft position sensor.
Pull a couple of plugs and see if they are fouled or the injectors may not be firing.
You unplug the injector connector and install a noid light in the harness. Crank or start the engine and the light should blink if it is getting power. Reconnect the injector and using a stethoscope and place it on the injector and you should here a clicking noise. In all probability the injector should be working unless the nozzle is stopped up preventing the fuel from spraying.
no Most of the time white smoke is caused by antifreeze burning in the cylinder. Leaking injector s can cause white to blueish smoke.And that's alot more common then antifreeze getting into your CTD. Also antifreeze will almost always lock you up , due to the higher compression of the CTD. Gas engines have a much lower compression . They will sound horriable but burn it. CTD will crack. Check leaking injector, or turbo oil.
Check the computer codes. Borrow, rent or buy a code scanner at a local auto parts retailer. You might be having a problem with the O2 sensors, egr valve, throttle position sensor, fuel injector or other sensors that could affect the performance of the injectors. If an injector is sticking you might need to replace it. You can also add a little injector cleaner if that's all that's wrong but stuck injectors are often more difficult than that.
check the fuses
Are you getting power to the system?
plugged up fuel injector or bad injector itself.
the computer and the ignition module give power to the injectors.
Do injectors have pulse?* (If not read below) Check fuses, ensure fuel pump is operating, ensure fuel line is not kinked restricted or damaged (between gas tank and fuel injector rail), is gas in tank, is there spark to spark plugs? *Use noid light to see if injectors have pulse while cranking engine. If problem is not found repost with as many symptoms as you can find.
I never heard of any fuel injectors getting damaged from running out of gas.
I'm not a mechanic / technician but I BELIEVE if the fuel injector is restricted so that the proper air - fuel mixture is not getting to an engine cylinder , that an engine cylinder misfire can occur ( that is only one of the causes of an engine cylinder misfire )
could be out of gas, maybe a blockage in the fuel line, are the injector getting power??? is there enough presure from the fuel pump it needs to be a minimum of 25 psi just to open the injectors , and the fuel rail could havea blockage as well
Check the injector pump and the fuel pump. If they are working and free of clogs, check the fuel lines. They rarely have a problem, but it's a good idea to inspect them anyway. Also make sure the fuel filter is allowing the fuel to flow.
When all fuel injectors are stuck open, this generally means that the injectors are not getting the right voltage. You will need to not only check the voltage, but make sure the injectors are receiving the right signal.
Take the wire off the injector and use a volt ohmeter to test it. Hook the red or + lead to the wire and ground the -ngeative wire. Have someone turn it over with the starter. If they are getting power the volt ohmeter will register it in pulses.
they are getting longer for the only reason that seasons are changing. they are getting longer for the only reason that seasons are changing.
If it has a carburator it cannot have injectors. If it has injectors it cannot have a carburator. Take the throttle body apart and clean it very well with carburator cleaner.
