Help! Recently my truck has started stalling. When it does, it beeps at me, and most of the time catches itself, but sometimes full on stall. Here is a brief history.

Sunday ) Stalled on my wife, she got on the shoulder, restarted with no hesitation, ran no problem all the way home (30 miles). I test drove it when she got home, stalled once, but immediantly caught itself and ran just fine.
Monday) Ran fine.
Tuesday) Ran 67 miles, stalled 10-15 times, always caught itself. Did the key trick that evening, pulled code "P2509 - Ecm/pcm Power Input Signal Intermittent". Did some research on here, and tracked down a wire on my passenger side battery, negative terminal that was loose. Tightened that, thought it was fixed.
Wednesday) Ran fine all day. That evening while in parking lot, truck idleing in drive, full brakes, all stop, dies. Immediantly restarts, runs fine after.
Thursday) Multiple stalls while driving 35 miles, only once a full stall. Did key trick, no codes. Thought maybe it was my fuel filter, since I've run bio the last few tanks. Replaced my filter today during lunch break. Stalled 3 times driving back to work. Key trick, again no codes.

I'm at a loss. Could be fuel pump, but wouldn't that throw a code? Ideas?

 

I'm guessing I'm going to have to take it into the local dealership if I can't find a easy solution tonight. This problem will probably be covered by my Cummins warrenty I think, and hope.

 

let us know what you find out,mine is doing the same thing and no one can figure it out.thanks

 

sounds like a short somewhere like a wire rubbing somewhere

 

I have to agree with the other guy (Rich),,,, Sounds like an intermittant wiring/connection issue perhaps in one of your harness's/plug-ins,,, Good Luck,,,

BTW,,,, Where did you pick up the Nittos?????? what sidewall rating are they???

 

Could be an ignition switch. I've seen these cause some weird problems before. Just a thought.

 

Welp, I figured it out last night. It's my own stupid fault. I got really irritated with my inability to figure this out, and then I got an idea. I started my truck, and let it idle while I jiggled every wire I could reach. I eventually grabbed one, and boom, truck sputtered and died. Booya, found it! Traced it back to my driver side battery, loose at the positive terminal. Geez. When I tightened the loose ground I found on Tuesday on my passenger side battery, I was patting myself on the back and enjoying a celebretory beer, I didn't even look at the other battery. It seems, when I put my two, brand new batteries in last May, I didn't do a good enough job. Ugh, a week of frustration and it's my own rush job. Lessons learned.

RiverRat2 - I got my Nitto's at NTB, I know Discount carries them also. They are E-rated, I don't know the weights off the top of my head.

 

Glad you figured it out!!!!

NTB on the Nittos ehhh,,,, Ill check em out,,,, Did they have em in stock or have to order them??????


GO Tigers!!!!!! Kicked them Horns/Tea Sippers around @ the college world series!!!!!


T U Sux!!!!!!!!! "Saw em Off!!!!!"

 

The store I used in Katy didn't have them in stock. However, they have a warehouse in Houston that had 4 in stock. After a $300 deposit, they got them in 2 days. Overall, I had a very bad experience with NTB, and regret not using Discount. But that's just my personal experience.
