Have someone help you, then using a can of starting fluid, spray some fluid in the intake while your friend tries to start the engine. If everything ELSE is working properly, and the engine starts briefly with the starting fluid, there is probably an issue with the fuel delivery. It could also be related to EGR valve, especially on a vehicle that is getting a little older. Sometimes a plugged EGR circuit can cause problems with the engine.
If the problem followed the fuel injector then it is a bad injector. If the problem stayed at the same hole with a different injector then it could be bad wiring.
No it is not a fuel pump problem. It either has a grounded are open circurt. Check wiring to injector. May just be a bad INJECTOR.
the harness could be bad on that injector chech to see if its firing and if it is then the injector is bad
Try checking fuel injector that is what the problem was with mine after checking everything else i replaced injector an fixes the problem
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.
I had a similar problem. Turned out to be a bad solenoid on the fuel injector. Required the replacement of the entire fuel injector. After that, the problem was solved.
Disconnect the negative battery cable for 5 minutes. Note that the light will just come back on unless you repair the problem.
Pull it out and look at the spray pattern.
Peak injector current has not been reached (non-turbo) or a problem with an injector circuit (turbo). Check the injector(s) and electrical harnesses.
I would like more info on what your problem is. oldgrizzly
Replace the fuel filter first, sometimes they can be the problem. But usually it's a tired fuel pump.
on the fire wall under relay center this is the fuel pump fuse injector fuse is in the fuse block injector a if any at all what is the problem any whay.
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
possible problems are: The fuse is blown, or the injector is bad, or the wiring to the injector is bad, or the computer is bad
Injector pressure sensor system performance problem.
It can be battery, faulty coolant temperature sensor, faulty cold start injector, malfunctioning fuel system, injector leaking.
yes a bad or partially clogged injector could cause this problem
It means your fuel injector or computer are messed up. Your injector could be very clogged. Somewhere in your fuel system you have a problem. You should have a scanner plugged into your car and get the code, it should lead you to it or near.
If you mean the fuel injector for the #4 cylinder isn't working the answer is simple, either the injector is bad and needs replaced, or the connector has gone bad/ the wires are shorted out. Put an injector pulse tester on that injector (most people don't have these so you'll need to get it tested at a garage), if the injector doesn't fire when it's tested separatly you need an injector. If it does fire that means the plug/wire is the problem.
TIME TO GET THE TRANSMISSION REPLACED
It is likely an injector problem which would require you to replace the injectors.
this problem is usally the injector liners!! you usally have to buy a tool to pull these out with
