Anyone get a new FSD/PMD and have it fail within a couple of weeks?

The FSD is mounted to a FSDCooler on the inner fender using a new heat transfer pad.

I would contact EDAM (or whatever his name is) and see if he'll send you another one. I suppose it's possible you got a bad one. Mine has been 100% (knock on wood) since I replaced it.

Never had any new ones go bad that soon. Stanadyne warranties them for 12 months when mounted correctly. Mounting on the fender well is not a good location. There is very little air circulation there to remove the heat from the cooling fins. It could very well get way to hot there.

 

[DavidPhillips]

Could be something else. Do you have the other one for comparison or is it toast?

Any codes? What's it doing? Did you buy a kit or mount the FSD yourself?

 

[jifaire]

Never seen a new one go bad before ... but it's not beyond the realm of possibility. People make 'em, people screw 'em up every so often.

That's why we get warranty, right? Get a new one from the dealer.

I've had a Brand New one go bad pulling it out of the garage with maybe 15 minutes run time on it, remote mounted to a FSD cooler out of the engine bay.

Thanks for the quick replies.

I realize it may something else, but it's strange that it seems to acts similar to the way the old one did as it was failing, this why I'm askin you guys!

The old one sort of works also smells like the electronics are cooked.

No MIL, but guess it may have stored a code and not displayed the MIL (?).

I mounted the new eBay FSD on to a FSDCooler using a new heat transfer pad. Then moved the "cooler" off the intake to the drivers wheel well until it warms up, then move it totally out of the engine bay.

 

[DavidPhillips]

Possibly if it shut down and then was OK when you started it back up there may be a code.

 

[corolla]

It didn't start right away I did have to wait about 10 minutes.
Thing is it's cold here like 3 F.

I touched the "cooler" and the FSD it was not even warm.

The only reason I'm panicked, there's still warranty on the unit, but I have ship it and wait (should bought two!?!)

 

[DavidPhillips]

Mine was dying recently. I have a new remote FSD and also I have the original PMD that I believe is still good.

I switched PMD's and problem remained. Sometimes it would take 5 or 6 seconds of cranking to start and would light the light. Others it would start right up and not light the light.

If it coded as it shut down and started normally when it did finally start you would not see it.

 

[jifaire]

Oh, I doubt that you cooked it ... not usually a wintertime thing. Your old one should work OK in the meantime, I would think. Call the vendor ... maybe he'll ship you a new one while you wait to ship the old one back? You might have to give him a credit card number to hold until the return gets there.

Anything I've ever had issues with, the vendors I use have been happy to do that.

BTW - the PMD doesn't have a DTC 'code' of its' own, so don't expect to find one, but what you might see is other IP-related codes... that was the reason GM changed out so many good injection pumps before somebody figured out the FSDs were getting cooked.

There is a doagnostic procedure for testing FSDs, but I can't remember what it is. Ask gmctd.

 

[gmctd]

What's the 4-digit code on the transistors?

 

[SuperBurban]

There is a doagnostic procedure for testing FSDs,

I think it was about a month ago. I suggested the thread should have been made a "sticky", but I do not think it made it.


With so many problems PMD related problems and someone shows how to test them, it should be front page material!!!

 

[gmctd]

That procedure was a simple short-test intended to protect the exorbitantly-expensive Bacharach\equiv flow bench from damaged FSD modules.

The only practical test is substitution.

So - what was the 4-digit code on the transistors?

 

[corolla]

I need to take the FSD off, then I'll post the codes.

As an aside the old one has BM0439.

 

[gmctd]

That one is from 2004, 39th week of - or, 043rd day of '99, julian

 

[corolla]

Yea

I can't believe I'm getting excited about seeing the check engine light!

Well it stalled again, but this restart (within minutes of stalling), had the MIL on.

Won't be able to read codes until monday though!

 

[corolla]

MIL Code

Got the code it's P0251 !

I have had this code once before and only this DTC. This is with both the old and new FSD.
As you can see I don't get the code all the time.

I"M very confused only have about a week to return the new FSD for "warranty".

 

[corolla]

Follow up

Returned the new FSD, vendor sent a replacement all was good for 1.5 weeks.
the today it stalled but restarted right away. No MIL, just shut off?????

Any thoughts.

Still have optical sensor filter harness installed? Mine threw a 251 'cause of that little booger.....
