how in the heck did you figure that out ?

 

Went back to basics and checked all power readings from the wires starting with the pcm. It was pure luck honestly but hopefully someone having the same problem will have somewhere to start from.

 

I believe I probably found the problems that was drawing down my 5 volt supply voltage from my PCM. Since my DVM shows that my wiring was not right and I only was getting 6 ohms at the pins connecting the injectors of #5 and #6 to the PCM, I pulled off the Plenum on top of the intake and removed my Injector Harness to find missing insulation at the connector plug connecting the Injector Harness to the main harness leading back to the PCM. They were partially shorting together, making the resistance wrong. Three of these wires with missing insulation go to a sensor connector on top of the Plenum. Cost of a new Dodge Injector Harness was almost $400. Instead of wasting my money on that part, I elected to repair the harness. I got wires from another connector plug kit they had in stock that had identical wire ends crimped on them. I am now in the process of removing one wire at a time from the connector and sliding the new wire into the connector and soldering them into the wires with a good strong thick heat shrink tubing to cover the splices. The end result is my spending $50 to repair it, a little of my time, and saving about $350 over buying a new Injector Wire Harness. Plus, I will also have a real heat shield over the harness where the damage took place which was all within the first 8 to 10 inches of the Injector Harness from the Wire Harness Plug back toward the injector connectors themselves. The rest of the wires are held well off the intake manifold with plastic pieces that plug into mounting holes and are taped to the wire harness part that goes to the injectors. It is the opposite end of the Injector Harness that needs added protection. I do not know if the rodents chewed it off, or heat related, but I do know, back under the harness where nothing could have chewed into it, there was missing insulation, which I can better protect with these spark plug covers that withstand about 1500 degrees of heat and reflect that heat. Cost me $12 for two of them. Large enough inside diameter to slide the injector wire harness inside of them. They are nicely constructed and heavy duty, so will not have this problem again with that injector harness. I want to thank everyone for your posts, because what you posted surely allowed me to troubleshoot my problem. I may not have a Dodge Truck, but your procedures are certainly the same for a Dodge Caravan. It was the many other posts I read that allowed me to gather enough information to troubleshoot this problem myself saving me hundreds of dollars over the dealer repair costs. Thank you everyone.
