Hi folks,
Trying to get my 2000 Dodge Ram 1500 (5.9 V8) back to full speed.
Started up and pulled out one morning last week, but the MIL (Malfunction Indicator Light) lamp lit immediately. Truck was running a little rough, so I returned home.
I checked the error codes, and saw only code P02024 (improper voltage at fuel injector #4).
Once under the hood, I realized that some critter had crawled under the hood and chewed off the power wires to fuel injector #4.
I checked the resistance of injectors #2 and #4, and they matched at 13 ohms, so I don’t think the injector itself is faulty.
I repaired the two power leads to injector #4, and compared them to those of #2. With the engine off, one lead has a solid connection to ground (as it should) at each injector. On injector #2 (working correctly) the other lead has no connection to ground. But, on injector #4 (causing the error), the second lead has a high-resistance (3 kilo-ohm) connection to ground.
This makes me think that something has shorted in the PCM circuit controlling injector #4.
Does this make sense? Is this something I can tackle myself? I’m reasonably competent with electrical systems.
I thank you in advance for any suggestions, hints, or comments.
Cheers –
