6.5 keeps shutting off any help?
 

i just got a 98 3500 with the 6.5 td in it ,and it keeps stalling and sometimes it will start back and other times i have to wait a few mins,i tried replacing the in frame fuel pump that didnt seem to help, i heard people saying it was the pmd but i wanted to make sure before i spent that kinda money on it any help would be greatly appreciated thanx...:humm:

sounds like a pmd.

if you have another one or have a friend with a good that is the only way to test it

DTC codes first please.

The Pump driver is a very likely culprit in a ds4 truck where it just dies for no reason.

While there is no OBDII code specific to the PMD failure, there are codes that associated with it when it fails. Kinda like a cascade failure effect...

I have the same problem with my 6,5 td Tahoe...could it be a "sticking metering valve"??

Please start a new thread and give your year...

x2 no hijacking!:nope:

would a fuel filter cause this??

also something called a super boost sensor when plugged in the actron obdll tester:argh:

You mean the stalling for no reason?

Nope.

At least, not what you describe.

Super boost sensor?

Never heard of that one.

If you can wait a while, you can buy used pmd's on eBay for 30-40 bucks.

As with all things from eBay, you take your chances. But if you swap one in and your problems change or go away then you can spend the coin on a new one.

I'd recommend the kit from Heath diesel, but there are others out there....

pmdcable.com has good deals too

got mine on ebay! workd great and for 60 sent to my door in 3 days you cant beat that, most r used but tested, anyway its a cheaper route!

Don

Be warned: A lot of the used Ebay PMD's last less than 60 days.

An eBay PMD should be used as a "tester" or a "git back" spare.

Once you confirm the PMD is the issue, you should pony up some dough for a good one like those sold by heath diesel or PMDcable.com.

Unless you don't mind taking your chances or dealing with more frequent breakdowns.....:ouch:

great white told me on my 99 that it was bad grounds on the back pass side of the motor behind the intake manafold and i did that and all problems solved

it was the pmd thanx guys:jump:
