A few weeks ago i ordered a used Pmd off ebay and was waiting to put it on until my other one screwed up, well i didnt have to wait long, i was drivin down the road the other day and the truck died and before i got back home it did it again(which was about 3 mins later). Now considering this is my problem and the used box i got even works, where would be the best place to mount it. P.S. over the last few years the truck has did this twice and both times replacing the PMD has fixed it, just hope it does this time

I say up high infront of the radiator. The fan will keep it cool at idle. Check fuel supply pressue/operation at idle.

on the pump

On the pump until you get a remote mount kit and extension harness to get it out of the engine bay, too many have failed mounted in stock location for me to have confidence in that location. 9465 this is probably one of the most debated topics, I will say from my experience my PMDs have lasted longer off pump on remote cooler, my current setup is a Heath remote mount kit mounted just behind the license plate.

Over at the Diesel Page ongoing experiments of the SOL-D replacement module have had some setbacks but the mfr is standing by the product it seems and exchanging the test modules for study why they failed. Until the SOL-D is proved to be a reliable product, my recommendation goes to the Heath setup mounted outside the engine bay.

this link shows whre i put mine. i check temps every shutdown and its staying nice and cool.

If this new Sol-D thing works out to be a long term, super-reliable deal, then you might mount your Stanadyne PMD in the nearest trash can.

For $500 a pop , I'll run the FSD's I have till they die.

There's certainly a price vs. value equilibrium, and depending on which side of things you happen to be on, "old school" PMDs can make a lot of sense.

I'm interested to see what, if any, tuning options this new thing will open up.

Do you mean calibration resistance? I'd forgo that for TDG's optical bump. Although I'm running a #7 and the bump.

it says kennedy diesel.com is down, does any body know the price of the stuff ill need for moving it in front of the radiator

Heath's kit is $395 final sale for me was it comes with extended warranty Google for Heath Diesel, JK's was in that ballpark maybe a little more IIRC; JK's uses a finned heat sink, Heath's is different style FSD/PMD bonded to heat sink plate, I failed mine 3xs on the finned style cooler in engine bay, recovered it twice with retorque of screws, went the Heath route after last fail. Finned or non finned get it out of engine compt IMO.

TD,

Great advice! I was experiencing randor 'fish jerks', mostly at higher rpm and when hot, granted I'm running WVO 99.9% of the time so the PMD wasn't getting cooled with 160F oil running through the IP, but then I began to experience random stalling. It would restart, but stall again soon after. No codes, good fuel pressure (either diesel or WVO). Bought the Heath kit, no more problems, even sorted out that wierd high idle I was experiencing at times on the WVO. Thanks for the help on that one TD, we drove 840 miles over thanksgiving without a problem, only used about 4 gallons of diesel all weekend!

...only used about 4 gallons of diesel all weekend!
yeah, yeah, yeah.... we're all jealous.Censored Seriously jealous! I don't have a McDonalds or the like down the street for me to go get veggie oil from. Do you get that stuff for free?

Free indeed! It's a bit harder to come by in the cold, dumpsters look pretty bad without the summer heat to settle them out. I get about 15-20 gallons a week in those 5 gallon totes now, and have begun dipping into my 300 gallon 'reserve'. If its 50F outside and sunny I can usually score 20 gallons or so out of a clean dumpster at a local chinese place.

Get you a rosebud tip and a torch heat up the waste tank 1st mite flow a little easier

bout a month ago someone on ebay was sellin some little mountin plates for like 8 bucks but now i cant find them. is it possible to just make my own mountin bracket and just order the wiring harness

bout a month ago someone on ebay was sellin some little mountin plates for like 8 bucks but now i cant find them. is it possible to just make my own mountin bracket and just order the wiring harnessYup. Did you read the PM I sent you? Kennedy sells the extended wiring harness. Find a flat hunk of aluminum about the size of a liscense plate, drill four holes to attach the pmd, mount it someplace outta the engine bay, and you're all set!):h

Does anyone else here have any significant miles on a setup like this?

Howie E has had his Heath mount on for quite some time mine has only been on for 6 mos

Forgot to mention... you'll wanna use GM's heat transfer paper or other between pmd and aluminum.

I mounted mine through the nostril in the bumper. It sits nice and snug in the bumper right behind the license plate. Honestly, the pmd doesn't even get warm anymore let alone hot.

the PMD i ordered off ebay says its the newest version, whats the diff. in this one and the one i got now, and it also says it didnt come with a resitor, what is this and will i be able to use my old one

Make your own wiring harness extension. It is very easy, just need a few spools of wire, heat shrink tubing soldering iron/gun and an old stock pmd harness. Cut the old harness in the middle and then simply solder in the lengthened wiring, heat shrink the connections and cover them with wire loom. Then you only need to connect the red and black wire coming from the back of the injection pump and they can be connected the same way. This all costs about $8-15 and about 1-2 hours time. I have been running my 6 foot extension in front of the radiator for about eight months and never had it heat up at all.

on the pump here also.
For the record, when I have to put a pump on a truck, the PMD goes on the pump, even if you have a cooler. I have one time put it back on a guys cooler, after he signed a statement to the fact he had not one minutes worth of warranty on the pump with it mouunted that way. If I can't get stanadyne (who has 'buildings full of engineers') to agree to warranty pumps with remote coolers, why should I? ( i guess I need to hunt down that bulletin again)
I have yet to warranty a pump, or have one come back out of warranty, with a failed PMD, due to it being mounted on the pump.

Remote mounted with a heavy-duty heat sink in the front bumper between the two "nostrils". PMD does not even get warm anymore.

There seem to be a high percentage of PMD failures out there. I cannot believe that pump mounting is great long term. Yes, I know, pump does provide cooling, but not when the key is turned off. Remote AWAY from engine heat is way better. The idea of just doing a heat sink above the engine manifold is far, far worse than leaving it on the pump. Stanadyne doesn't want to admit their idea wasn't the best. They are the same people that came up with the theory that mounting your PMD on a heat sink will cool it too quickly, and cause the epoxy inside and board to seperate/crack. Come on, only if you drop this puppy in a bucket of ice water maybe on a hot summer day.

I had to add rubber grommets between my cooler and the trucks sheetmetal. The mounting screws vibrated loose and the driver didn't like the extra movement.

I disagree unless you are seeking warranty pump replacement, GM will not warranty an off pump mounted FSD, probably won't cover IP either, if you still have warranty on IP; I recommend run with 2, one on IP unplugged, and other on remote cooler in air box or inside fender so turbo is pulling cool air across fins or plate even just running at engine idle speed. If plate mount fails then swap with pump mounted one, remove evidence of cooler and get new one under warranty.

This weekend when doing TDC offset learn, at extended idle hood open, on 60F day fuel temp was 150F, that is the cooling medium for a pump mounted driver, so the lowest it could possibly be is 150F, when running hood closed under hood temp will be much higher, because PMD is also subjet to engine/engine compartment heat as well as the heat it self generates.

My bumper mounted FSD on Heath remote mount cooler plate surface temp was 90F on 60F day extended idle running doing R&D with T2 vs Snap On MT2500 testing and TDC learns.

As far as Stanadyne/GM not honoring a non pump mounted PMD replacement, several discussions evidently on that; rumors exist in several circles that GM forced that location and it wasn't Stanadynes preference either, my opinion and just that, is that Stanadyne nor GM were ready to own up to it for a wholesale campaign of replacement as it would cost a lot of money. Condoning cooler mounted FSD/s would lend credibility to marginal design claims needing to be fixed on entire fleet of trucks.

Risk assesment said they will fix them as required, and since not every truck has the problem cheaper to fix them than replace all outright, notice the 10yr 100K special policy has been extended to 12yr, 120K mile, not too much pain there either as fewer and fewer 6.5 fall into that category as they get pulled of the road for newer model trucks.

Now one more thing to add to the FSD/PMD issue, loose connector sockets will cause same symptom as a bad FSD, to test get a same size FSD pin and insert in pump or extension harness socket female pins, a loose male to female fit will cause an intermittent fault and shut down truck, found this over the weekend also. So it's not always FSD/PMD at fault need to check basics 1st before condemning it to trash pile.

The loose pin conditon is the reason we now sell PMD/harness kits.
That and for some reason people think that wire is a handle. i cannot count the times someone has walked in carrying one by thehandle. Better yet is the guys who buy one andn pick it up off the counter by the 'handle'
Used to be you just got a PMD, mounting pad was even seperate for awhile. then the pad was included. Now you get the harness piece also.
