Try downloading Opera Mini for your phone. I'm posting this right now on that browser on my BlackBerry Pearl Flip over wi-fi. Doesn't help your Durango trouble but might help your internet on the phone trouble.

 

I'll definately try that.

Also, for whoever consolidated my threads- Thank You. It shouldn't be a problem anymore because I've learned about copying links and reusing them to navigate.

I'm still hoping someone can look at their wiring diagram and tell me the 3 crank sensor wire colors and if they run straight to the pcm. If so, then I'm going to bring the engine heat up to where it begins to die and be waiting to test with my meter.

 

im guilty of merging the threads, id have done it sooner if i was paying attention to the usernames posting the threads

 

Ok, found the burning smell source, it was the ign switch- which was part of the problem.

Got it and the crank sensor replaced.

She's now runs fine, but dies after a few minutes. No codes or anything at all, no stumbling- engine dies just by itself.

It has a new duralast battery, plenty of fuel. It seems as though the ign switch was just part of the problem.

Any suggestions?

 

Check the relay, swap it with one of the same numbers.

 

I've been looking through the service manual and there's an ASD (auto shutodwn relay) that seems to power the things needed for the engine to stay running like the injectors and powers the o2 sensors and probably a bunch of other stuff when it's tripped. See if you can hear it click right before or as soon as the engine shuts off. Since it's not stumbling anymore and just plain cutting off maybe that relay is losing power or something. Either the PCM or ignition switch powers it, or could be tied to both so either can shut it off maybe.

Just a suggestion, it could be a number of things.

 

Ok. We got somewhere today. I thought I had updated this thread earlier but I guess not.

So the d will idle for quite a while then just die. No stutter, no codes. Drives ok under throttle but will die if I let the tach get too close to 1k.

Checked and swapped the asd relay- nothin'.

Pulled the iac connector after start up and cha-ching......it wouldn't die. So something was killing the iac.

Pulled the low vac sensor and plugged the iac back in (threw a vac code of course) and it wouldn't die- so now I'm getting excited.

Cleaned the contacts on the vac sensor, plugged it back in and cleaned the iac- it was filthy.

So now it doesn't die AT ALL. It idles a little funny. Took it on the road and when letting off the throttle the tach will dip to around 350, every now and then it goes too low and dies.

So I think we have it down to the IAC now. Took it back off and the servo is binding pretty badly.

Got a new one coming in the morning, which should make her purr nicely.

So, this was a compounded problem:

PCM contacts needed some lithium
Bad Ign switch
Vac sensor connector dirty
IAC crudded and sticking

I'm going to download the pdf on cleaning the IAC port for good measure as well.

I let you guys know if she runs fine with the new IAC.

 

glad to hear you got it all figured out, hopefully you are correct

 

did you ever get to the bottom of you ecm problem.i have the same truck (new purchase)replaced all sorts off sensors. It is only when It gets warmed up all the stalling issues begin.when she cools down, starts right up.one thing I've noticed, ...traffic/city driving is when she heats up and stalls..highway driving i get much longer miles before she starts to shut down..anyway, can you give me as much info on this ecm or pcm, and what exactly you did. And has the new computer helped ? I'm on my last nerve with the truck...i also smell that burning after some time on the highway.. Anyy suggestions

 

I'm trying to figure out what a VAC sensor is?


Also what about a Fuel pump......Just throwin that out there for the old thread.

There is no ECM on a Dodge, the main computer is a PCM. Anyway, what you are describing is a PCM failure. An idea to try, put a bag of ice on the PCM after checking the connections to it and go for a ride, if it runs like a champ replace the PCM, if not look further.
