hey guys, Im asking this one for a buddy of mine so I dont have a ton of info: the truck is a 99 3500, 6.5, bone stock 270k miles. He knows the module that everyone has issues with was going out as it would stall at times but would restart with no issues. This past weekend he shuts it off and now it will not start at all. Can this module just fail or believe its something else? He says he checked the lift pump and can hear/feel it running. Any further suggestions? I hope this makes sense

 

1) well yes PMD can fail to no start

2) just because you hear the LP does not mean it working

Test the LP buy open the bass T-valve near T-stats see if fuel comming out when you turn key on

Here link on how test the PMD

Hope this some help to you

 

Thanks for the help! Ill pass it along, Im a Cummins guy and hes new to diesels so its a mess

 

should have told you if he has bad PMD when get new make sure he gets with heatsink and a 6ft harness and move it to the front bumper get out from under hood to much heat there

 

yes, move it to the front bumper when it is replaced. they last a lot longer when they are away from the engine heat.

 

thanks for the help. Ill pass along the info

 

carefull if u offroad pmd could get muddy or wet n also fail been there. N there not cheap! I put mine behind front head light on fender seems to work ok so far.
