My PSD Died for no reason Why?

Anyone:

I was setting at a light today, and my 03 F250 SD 7.3L PSD died for no reason. Before it happened it sounded fine, I had just looked over my gauges as I always do (good habit) everything looked fine; then wahlah it just died. I turned the switch back to off, and tried to re-start, it cranked fine, and started right up.

I've owned this truck since 2005 and never had that happen before. I recently replaced glow plugs, wiring harnesses, valve cover gaskets, GP relay, and oil-filter and fuel filter approximately 2 months ago using all OEM parts.

Any idea what could have caused this? No check engine lights; absolutely nothing popped up. I scanned it and no codes appeared. I'm baffled.

Any help is appreciated if anyone else might have had this happen before. I've owned probably 8 PSD's since the 90's and never had this happen on any of them. Although I'm just now really starting to learn about working on them. Let me know your thoughts.

What's the situation with your CPS (Crank Position Sensor)? Has it been replaced in the recall campaign? If you've had 8 PSD's you Must be aware of the problem they have with the early CPS.

What are you scanning the truck with? Are you sure it works on our trucks (most don't). There might actually be a code that would help. Otherwise, think about carrying a spare CPS just in case (everybody should...) and wait for it to get worse so you can fix it!

My truck did this a while back (5 or 6 years). It was the CPS (the old style) It stalled 3 or 4 times in a couple days. I replaced the CPS and it never did it again.

Yes CPS was replaced in 2007. I'm using the code scout II.

Yea, that's not gonna do it... It doesn't have the Library for Ford proprietary Or diesel codes. I'm not saying it'll never do anything for you, just that when it comes back "No Codes Found" it's not an indication that there really AREN'T

This could be an early IPR issue, all sorts of stuff really, and maybe just the beginning of something that will develop into something more consistent (or might never happen again!)

If it were me, and it happens a second time, I'd change the CPS, put the old in in your glovebox as a spare, if it continues you didn't lose anything because you should have a spare anyway

Ok, thanks for the info. I'll replace the CPS again, however, what do you recommend for a diagnostic scanner. have the OBS Code scout II, but what do you recommend for the PSD's. I've owned quite a few PSD's, but just now really digging into them and learning how to work on them. Always had a mechanic in the past, but these days dimes and nickels are getting harder to come by. Thanks for the insight on the CPS too.

Hands Down, and I think pretty much everybody would agree, what you want is the AutoEnginuity w/Ford Enhanced package. You run it in "any ole laptop" for around $350. If you're doing more than your truck, the Domestic Package (US Big 3) is a Great thing to own too (for almost twice that)...

Because of the GVRW, the diesel, plus the fact that our system is Not, strictly, OBD-II but rather a variant called SAE J1850, there's nothing else out there that will come close for that price
