Hi; my first post. I have a 95 GMC , 300,000 k, with the 6.5 diesel that seems to have recurring pmd issues. One of the replacement advertisers claims a weak injection pump will burn out the pmd, I can't find any supporting references and am looking for input. Thanks

How is your PMD mounted? What PMD brand are you using?

I only use the truck occasionally. After the initial failure about 10 years ago, I relocated one , can't even recall the source, to the front bumper, which worked well Until 2 years ago. I got one off Amazon, a knock off, which worked well for about 3 months, strange part being when I connected it directly it would still operate. Since that time I've been driving the truck with the PMD, on a heat sink, lying on the intake manifold. Quit again the other day. If I'm going to replace it again, I'd like a recommendation for a dependable brand as well. thanks.Quote:

Correct mounting and cooling is vital to long-term success. Can't be sloppy about it or use cheap parts. These modules generate considerable heat while in use.
