What are the symptoms of a PMD about to fail?

What are the symptoms of a PMD about to fail? I know I read it here some where, I got a 2000 6.5 TD, 126k, and driving down the road the motor will stop. no sputter or cough just stop. I put it in neutral or Park and it re starts easily.

I plan on replacing PMD, oil sensor, battery cables and lift pump. anything else I need to look at? this isn't a daily driver, just an excuse to get away from Mrs Drago

This link is a good place to start. Check/clean all of your grounds too while you are doing the rest of the stuff.

I had similiar symptoms when my OPS failed.

Sure sounds like a PMD failure to me. Thats what mine always did.

That is the symptoms for Stanadyne PMD.

OPS should not be a factor in running the LP anymore.

Keep in mind that ignition switches also fail.

If you lose the dash/instruments but the radio and blower motor keep working-consider the ignition switch as a potential source of the problem.

cruise kicks out on it's own, like it's possessed. code 36, has appeared in one of my PMD failures,, but stalling with restart is #1

Check the grounds on the last intake stud (Pass side) and the one on the tranny dipstick stud.......Remove, CLEAN, reinstall tight.

Just to rule it out....

Found all the grounds, replaced the PMD with http://www.pmdcable.com/index.php?main_page=product_info&cPath=7&products_id=44. fired it up, let it idle for 15 minutes and drove at or near highway speeds for an hour with no problems. I'd have to say the problem is fixed. once again thanks guys. saved a bunch of bucks

Glad to hear!
