As an introduction I have owned and worked on GM diesel trucks since 1983. I still own my first one I ever bought a 1983 K5 Blazer. Anyways I have been a member of a different GM Diesel Web forum/page and other forums for a long time and discovered this site from a member on that forum about a year ago and I have been reading it ever since but have not been much of a poster but figured what the heck. Maybe this will help someone else or just give someone something to read at work when they are bored.

Well It happen as I knew it would since it is way past the Warranty and at about 160,000 miles. My 1996 6.5 TD Chevy Tahoe stalled and died on me going to Base this morning. It had its injection pump with PMD replaced about 6 years ago and at 80,000 miles under warranty. I never put the FSD cooler/ new PMD on it yet since I figured I would wait for this one to go and then do the upgrade. Well my wait has ended and it happen. Had the classic symptoms of it stalling and not wanting to start with no associate SES light. If I wait awhile I got it to start but it would stall a little farther down the road. I was able to nurse it back to the house and park it.
Funny thing is I found that after multiple short starting events of getting it restarted and running till it stalled again that I decided to open the hood and tapped a few times on the top of the PMD it started right off and I was able to drive it all the way home. This is a commom solution/ practice in my job for fixing things especially electronic by first beating on it and it still surprises me how many times it actually works.
Well I guess I will now have to go and get my new FDS cooler kit and install it.
I just would like to finish off by saying thanks to all that contribute to what I call basic gearhead talk on these boards since you usually will always learn something new or reconfirm what issue you think you might have without spending alot of time or money chasing an issue.

Mongo H53E
Welcome to the site from your handle am I correct in guessing you have something to do with 53E helos?

Before condemning the FSD try a retorque of the nuts under the black plastic transistor covers, may get you back on the road until you get your new remote mounted one set up; I recovered mine 3xs that way before giving up and going the Heath remote route, snug then about 1/8th turn more, 8-10"# is what I torqued mine to make sure to not overtorque that was inch #, studs holding transistors are fragile.

Retorqing the nuts has worked on the four stalling PMD's I have tried it on.

Not to knock Tex, but the PMD I got from him made the truck I put it on stall. I switched it for the one off my truck, retorqed the transistor nuts (all four were finger tight) and it hasn't stalled since.

Thanks for the good insight into retorqueing the nuts I will try that, never thought of that and that might be why when I tapped on it it worked again.
I do have a FSD cooler set up coming from SS Diesel and figured I might as well just do it since I am about to do the big drive back to the East Coast with the truck with trailer in tow in about a week and half for my new duty station.

Yes I am A pilot of the CH-53E as well as in a few other Sikorsky products, CH-53D, H-3, H-60. Been involved in maint and testing of them for along time. I am currently leaving my current operational command to go back to VA area.

Mongo is my Call Sign as I am a little larger then the average pilot.

Mongo,

Where are you putting the FSD? On top of the intake is a hot spot. I've got mine infront of the radiator to get max airflow and it's out of the engine bay after shutdown.

I'm with QM on this do yourself a favor and don't mount the FSD on the intake, the one I put there lasted 30,000 miles, others have had them die there also 25-50,000 miles is not unusual. Just hope to save someone else a few bucks and headaches.

Well I was going to mount it there on the intake and I guess I should have looked at Heath diesels version but I was in a hurry and could not get his website to work so ordered SS diesel one. Do you know if I can get the extension Harness from somebody to mount the new fsd cooler that is on its way in a better location. I may just have get by with this one and update it later since I am in a time crunch. I may just make my own extension harness. Thanks for the advice and

Heath and kennedy sell extension harnesses. Making your own is cheap and easy just soder in a 6 wire extension between the harness and the PMD connector and cover it with a wireloom.

Yeah thats right I remember seeing it on Kennedy's Website. Well then that is what I will do and thanks for reminding me about where to place it since you all jogged my memory I am alittle mad at myself since I knew better and had an idea how I was going to do it a long time ago but it had taken a back shelf to more pressing issues and my hurry to get the truck on the road. Appreciate kick in the butt before I did something I would have to fix later. Better to do it right the first time.
