What is a PMD?
So what is this PMD? PMD stands for Pump Mounted Driver. The same part is also called an FSD or Fuel Solenoid Driver. (One is GM terminology, the other Stanadyne terminology). It is a "black box" about the size of a pack of cards mounted on the driver's side of the injection pump.
When do you need a new PMD?
Simply put, if your check engine light is not on and you experience stalling, it is a 95+ percent certainty that you need a new PMD. If your check engine light is on, you need to get your codes checked. Auto Zone and others will do this for free.
What is the PMD on the side of the injection pump?
Tech Tip: If your truck stalls and will not re-start you can often get it going again by putting a cold wet rag on the PMD, or by carefully pouring a cup of cold water on it. See this page for pictures of the PMD located on the side of the injection pump. So what is this PMD? PMD stands for Pump Mounted Driver.
What are the contacts on the PMD resistor for?
These are the contacts that allow the resistor to make connection to the pins of the PMD. Also notice the two extra holes - these are to allow you to get a hold of the resistor if you need to remove it. How do I remove and install the calibration resistor?
What does a PMD resistor do?
The Calibration Resistor on your 6.5L Diesel sets the maximum fuel delivery volume of the injection pump. It is analogous to the maximum fuel adjustment screw on an old fully mechanical injection pump.
What is PMD on a truck?
PMD stands for Pump Mounted Driver. The same part is also called an FSD or Fuel Solenoid Driver. (One is GM terminology, the other Stanadyne terminology). It is a "black box" about the size of a pack of cards mounted on the driver's side of the injection pump.
How do you test a 6.5 injection pump?
To test the lift pump start the vehicle. Open the T-Valve for a minimum of 30 seconds and let fuel drain from the line into a container. If during the 30 seconds the engine dies or no fuel flows out of the line then your lift pump is bad..Nov 10, 2016

What is a PMD on a diesel engine?
The PMD is a solenoid pack that builds up heat and uses the injection pump, and the fuel running through it, to absorb that heat. The injection pump is in the valley of the engine between the cylinder heads and the heat produced by the engine is also absorbed into the injection pump.
How do you test a PMD?
Touch the probe of the test light to the pink wire terminal in the PMD connector. With the ignition on, the light should light. If not, diagnose the circuit. Next, connect the CLIP of your test light to one of the positive battery terminals making sure it has a good connection.
How much fuel pressure does a 6.5 turbo diesel have?
Fuel pressure should read between 3 and 7 psi at idle. Anything lower than 3 psi may indicate that the lift pump is not performing properly and should be replaced.
How much fuel pressure does a diesel engine have?
On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles. Diesel fuel is injected into the engine in very small amounts by electronically controlled injectors.Dec 8, 2015

What is a PMD in a diesel?
A Pump Mounted Driver (PMD) is the black box on the side of the injection pump on 6.5L diesels in GM vehicles. The PMD is a solenoid pack that builds up heat and uses the injection pump, and the fuel running through it, to absorb that heat.
What is a PMD on a fuel pump?
The PMD (pump mounted driver) is that small black box mounted on the side of your injection pump. It is a signal amplifier that powers the fuel solenoid.
What does PMD stand for in GM?
PMD stands for Pump Mounted Driver. The same part is also called an FSD or Fuel Solenoid Driver. (One is GM terminology, the other Stanadyne terminology). It is a "black box" about the size of a pack of cards mounted on the driver's side of the injection pump.
How do I know if my PMD is bad?
Furthermore, how do I know if my PMD is bad? The most common symptom for the pmd failing is a hard starting hot issues. You could be sucking air into the fuel system some how. Do you know how many miles are on that pmd or that injection pump? Those Injection pumps get 90,000 - 130,000 miles out of them.

How to check power and ground on a PMD?

What are the results of the PMD Microderm Device?
I definitely recommend following up the treatments with a hydrating sheet mask, like PMD’s Recovery Collagen Sheet Mask, which helps soothe and restore post-microdermed skin.
How does the PMD Microderm Device work?
The Microderm in particular uses spinning-disc technology and vacuum suction to tackle a variety of skin concerns like texture, fine lines, and blemishes—scars included.
How often can you use PDM discs?
The removable discs and the two caps are easily washable and can be used for up to three to four times before replacing. (That comes out to every month or so if you’re microderming once a week). PDM offers Replacement Disc Kits ranging in sensitivity levels for $20, which I find to be reasonable for the healthy, glowing skin they impart.
What is microderm used for?
The Microderm in particular uses spinning-disc technology and vacuum suction to tackle a variety of skin concerns like texture, fine lines, and blemishes— scars included. I’ll be the first to say that acne, in its most literal sense, is not my biggest skin concern, yet texture is.
What resistors are needed for GM injection pumps?
Since each pump will be a little different due to production tolerance, calibration resistors were needed. Typically, the bulk of pumps came down the line with a #4 or #5 resistor. If you do not know what resistor your truck had and want to stay as close to stock as you can, just buy a #5 resistor. Most people buy the #9 resistor - it is the highest number available, and will increase your maximum fuel delivery about 6%. Note that this will not affect mileage significantly, unless you are always at wide-open throttle! Remember this sets maximum fuel delivery, so if you are just cruising along, there is no effect, but when you are pulling a big trailer, or trying to get on a freeway, you have that little bit of extra power. Please note that your truck's computer (PCM) will only "look" at this calibration resistor occasionally, therefore, after you install a different resistor, it may take some time for it to take effect and make a difference in the way the truck drives. This is also why people are often able to go for some time without a calibration resistor with no problems. What it takes to trigger the PCM to learn a new resistor seems to vary with different years and software configurations, but most trucks will "look" after a TDC offset learn procedure performed with a scan tool, after about 50 drive cycles, or after an extended battery disconnect. If you are not in a hurry, just wait, the update will take place eventually!
Does the PMD on the right have a resistor?
The PMD on the right has a resistor installed; the PMD on the left has none. Looking at the picture above, you see that the calibration resistor has six drilled holes in a row - this is so the resistor can slide down over the six electrical pins of the PMD all the way down to the base of the connector.
Does PCM look at calibration resistor?
Please note that your truck's computer (PCM) will only "look" at this calibration resistor occasionally, therefore, after you install a different resistor, it may take some time for it to take effect and make a difference in the way the truck drives.
Can you remove a calibration resistor without removing the PMD?
The reasoning behind this is that your old calibration resistor cannot be removed without removing the old PMD which is nearly impossible (especially on newer trucks) without pulling the intake. This would require several hours labor and the price of the gaskets required alone is more than what the resistor costs.
