Part 3: GM 6.5L Diesel Won’t start Again
One of my Vehicles Currently in my stable is a 1994 GMC 2500 6.5l Turbo Diesel. It has about 300,000 miles on it. The truck is on loan to be from my father, (Thanks Dad).
A few weeks ago it started stalling right after start up. After starting and stalling a few times it would run fine.
Last week it started stalling while I was driving
This weekend it would not start.
I went to google what could be wrong. What did I find?
Basically the GM 6.5l Diesel has this issue with stalling. It can be one of several issues, but it is most likely the PMD (Pump Mounted Driver).
The Lift Pump is working and I am getting fuel out of the T fitting. So I placed my order for a new PMD and relocation Kit. it should come in this weekend and I should get the truck running. I will share how things work out.

did the remote mounted PMDsolve the stalling problem?
I have a 95′ 6.5 with the same ongoing problem
how difficult was the install?
Hello, I’m wondering if that solved your problem with it stalling. I’m having the same problems with my 96 1500 6.5l turbo. Stalling at start up and while driving. Started yesterday, this afternoon it started fine. Please let me know what happened with your truck. Thanks

my 95′ 2500 has the same problem too, where did you order the PMD and relocation kit? was it expensive? right now I’d pay just about anything to get rid of this annoying problem.
just installed the pmd with the relocation kit. didnt solve my problem, heard it could be the oil pressure switch.
It can be the O.P.S., but if it the OPS you wont hear your lift pump running.
