If you could get a known good pmd and try it before that mechanic does anything, that would be good. Might save you from buying a new IP.

Don't be suprised the if mechanic says the Injection Pump needs to be replaced.
There are very few mechanics that will properly diagnose a 6.5L today.
Most will misdiagnose and tell you it's the IP to fatten up their paycheck with your wallet.

The recommended PMD relocation spot is to mount it inside of the front bumper on a quality heat sink and cable.

Anytime you replace a PMD be sure to also purchase a resistor for the PMD.
The resistor is needed for proper PMD function.

The FSD one fits in the bumper you just need to drill a new hole between the fins so it aligns with one of the license plate bolts.

Just FYI, the PMD is the same.
The heatsink can be reused by getting another PMD and the extension cable.

Where's you heatsink mounted? If it is mounted on the intake, it is just worse than stock location.
Always have it mounted outside engine bay

I had the SSD one mounted on the intake. I don't know why they still sell them like that, it's terrible. Okay spot while the engine is on and fan is running but as soon as you shut down the truck it gets hot as hell. I had 2 fail there before I started researching. The whole engine conducts heat out that heat sink when it's off. Now, I know the PMD is sealed but putting it in the bumper seemed sketchy to me. I just mounted it in the engine bay above the driver's wheel well and never had another problem with it.

I have a grey stanadyne pmd behind the front bumper on a blue heatsink and I just put some rtv around the bottom side sections of the pmd so no water gets under it.It works perfectly.

Yeah I saw a lot of people ran them just fine in the bumper. I even read someone put it in a bucket of water to prove a point and it still ran. I used to drive that Suburban off road and I guess I was afraid I'd drive into a stump and break it lol.
