today I had to go look at a vehicle with a wholesaler I am trying to hook up with all was fine for the 100 miles drive there and 75 miles of it on the way home, seeing how we were already out and it had been a all day excursion, we decided to do our grocery shopping, so with a full truck of what used to be cold food the truck starts bucking and looses power like you would not believe,
I barely got it out of the highway and turned around , I managed to limp it into a auto zone, what luck I am thinking, I actually break down at a parts store (now you have to realize where I live, it is about 12 miles to town, and where I broke down was the next closest place which is about 18-20 miles away (nothing at all in between but highway)
just as I get int he drive she dies out , I hit the key and she fired up and pulled he rest of the way in, and there comes the check engine light (I think cool, at least I will have a starting point) so I go inside and this nice kid is at the counter, I ask is he will pulls the codes, so he comes out and says WOW that is a huge truck (I only have 35's on her) I say yea, I hope I don't have to pay for a wrecker! <grin>
Anyhow, the truck has code p2146, Cyl 1-3 shorted high or low, Autone scanner says circuit failure has been detected , probable cause,
1) low or high drivers shorted ( I assume they mean a relay?)
2)injector harness failure
3) faulty Fuel injector
Now some time ago i went to look at a used dodge (3 hours away) when I got there it had a similar issue when I drove it, only it was cyl 4,5,6,
I had read I think on this forum, it is a common issue to have the wiring harness go bad, I assume this means only the one under the valve cover?
is there any this else I should test before ordering what looks to be a 200 dollar harness?, I will be out of time again as I get to do Jury duty then leave for Iowa 1st of next month, so I don;t have time to make mistakes on stuff I have to wait days to get ordered in
I did a quick look but can not seem to find (and I thought I had before) find a diagnoses tree of what wires should read what ohms, hopefully I can test all of this easily tomorrow after I take care of some business in the am
so I guess the questions are
exactly what all do I need to test.. injectors?, wiring?, what part of the wiring? ect ect, I could really use some experienced help on this
also, while I have it apart is it really a good "idea" to replace all the injectors? and where can I buy good ones besides from dodge if I can afford to do it all?
funny thing is, I went and looked at his 2011 manual trans dually with 3777 miles on it....... maybe my truck got ticked off at me
