So on my way home from my work my truck started fine and ran for a little bit, i went to the bank and on the way out of the bank it was running fine than all of a sudden it died and would not start again... So i believe my PMD is dead?? my fuel pump is running but my truck will not start just turns over

If you determin it is for sure the PMD/FSD, locate it on the front of the vehicle away from the engine. Others, including myself have learned the hard way that even a good heat sync FSD set up will still fail. The heat after engine shut down under the hood is harsh on the unit.

see mine in the passenger side hole in the bumper, easy to extend with 4 ft of 14 or 16 guage wire, cut and solder one at a time, no errors. If you don't have a trans cooler on the passenger side behind the grill there is space there. You could quite likely have some other failure, any SES light?

[6.5SmokeStack]

no no ses light just said check gauges and wont start :(

so today on my way home i tried to stat my truck and it started right up... So i had my girl friend follow me back to my shop (work) and it made it there fine. But would you guys think its the PMD?

[grancito]

That's what everyone says, heat sensitive/ erratic, PMD.

haha go figure, well im going to order the new PMD with the number 9 resistor that comes standard in news ones doesnt it? and get the heat sink with it, get the gauges and the 4" exhaust :)

[grancito]

That's a kit offered by ss diesel, FSD with heatsync and #9 resistor. Get 4 ft or so of 14 or 16 guage cable for each harness wire and extend it to put the FSD/PMD in the grill area, or in the bumper. Or buy a harness extension.

[6.5SmokeStack]

alrighty, is the extension harness hard to install?

[grancito]

If you buy a ready made harness, you plug one end into the new PMD and the other into the connector you pulled out of the old PMD. To make the extension, cut one at a time the wires near the plug and solder in each piece of cable, first putting a piece of heat shrink insulation over the cable. Heat shrink available from Radio Shack.

so this weird... i manged it to get my truck back to my shop fine... Today i left it running, got it hot and drove it around the yard at my shop. It never stalled and ran fine. But since it stalled the other day and never restarted. Is that a sign of a bad PMD??

[grancito]

I think that it's the generally accepted cause, you should setup a new or used one on a heatsync. If you have the original, it probably does not have the "limp home mode" the model 34583 is suposed to get you home although not functioning well.
