Question about 2004 Dodge Neon
What do you mean by "and used a fuel injector?" Do you mean that you used a fuel injector cleaner, or replaced a fuel injector with a used one, or something else? From your description, it sounds like you believe that you have an ignition problem, which is why your comment about the fuel injector confuses me a bit.
You state that you have replaced the ignition coils, spark plugs, and plug wires. I take it that none of those actions had any affect. In your car, the ignition coil pack is directly driven by the engine computer. I would check the wiring between the engine computer and the ignition coil pack. If that wiring checks out, I would suspect that you have a bad computer. I would be a bit surprised if the computer were bad, but it is a possibility.
The pins you need to check on the engine computer connector are pins 9 and 10 in connector 2. Connector 2 will be orange (not green or white). The wires associated with these pins should be dark blue with tan and black with gray respectively. From what I can decipher from the pictures, it appears that the engine management computer is underneath the air cleaner box. You have to remove the air cleaner box to get to it.
To test the wires, disconnect (or remove) the coil pack and check for continuity between the coil pack connector (not the spark plug wire terminals) and engine computer connector. There should be no resistance in the wires. There should also be no continuity between either wire and ground (as long as you've got the ignition coils disconnected).
