98 6.5 Stall


Recommended Posts

Posted

I have a 98 3500 w/6.5 that stalls first thing in the morning after about 15 min and restarts immediately then runs about 5 mins and stalls again. When you restart, it will run all day. ANY help will be GREAT.

Have you got your PMD relocated ?

 

If not i'm guessing the PMD is shut and you have to get a new one and have it relocated, either in the front bumper or just somewhere it doesn't get hot...

 

This is a common issue with the "Detroit" 6.5 TD

 

Here is a link to BD's relocation kit:

And here is a link to the PMD unit itself

Don't just buy the PMD and replace it on the same location, get it relocated where it will get some cooling, this is the brain for your fuel pump, and it is a known problem that they burn out and act exactly as you describe...

 

You could actually just cut apart the connector from the PMD and relocate it by yourself, and then lengthen the wires and solder them together, but if you think you're not up to it just buy the relocation kit ;)

Does this condition ONLY stall the engine, or can it cause other symptoms? My '97 K3500 (bone stock) will run fine all day: starting, stopping, idling, A/C or heat, cruising, rain or shine... But on VERY rare occasions, it seems to slip into N and then stall. Sometimes, immediately after the stall, it seems to have no battery power to light the plugs or spin the starter (as I'm coasting along the shoulder) but the radio stays on. Then it'll restart, but the trans seems to be locked in 2nd. No DTCs; battery terminals are clean & tight; batteries are ~2y.o.; no other problems. When it runs, it runs like new, and that's 99% of the time.

    • Yes, and also pulling heavy trailers or a large camper up steep grades as well as descending grades such as the more rustic off road camping locations and using engine braking with that low gearing as well as soft ground can just suck the power . I realize pickups these days tend to have an over all lower first gear ratio compared to automatic transmission pickups from years back so that has helped a lot in its ability in high range but there comes a point if in four wheel drive the torque runs out at the wheels, certainly with a gas engine. They don't put two speed transfer cases on pickups for a cool factor, they have a function if one needs that massive torque to the wheels that high range can't deliver. 
    • Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....  
    • 4 low is really nice on steep boat ramps. 
    • Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.  
    • Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.
