My new DME failed. - rhudeboye - 10-19-2007

I purchased my 68 last year and via tis forum I quickly learned that the DME Relay is prone to failure. So i purchased the one below from Paragon, swapped it for the existing and threw the old one in the back.



Well, here we are a year later and my car wouldn't start. knowing that I had the new DME in place I assumed I wasn't getting spark. Called the good folks at RS Barn, as I planed on buying wires from them anyhow, and explained my situation. His first response "did you swap the DME?" This got me thinking, the old one was in the trunk and it would take 2 minutes to test. So I run in the garage and give the key a twist 1, 2, 3 times and no start. Swap in the old DME and Bingo! first try.



Have any of you experienced this problem after replacing your DME?

Did I buy the wrong one ?



More then likely, this is just part of my typical hard knock life.

Electronic parts are finicky. Yes, I have had a failed DME "come back to life" sometimes after just taking it out and rubbing off the contacts and reinstalling. some other times after dropping it on the pavement and then reinstalling it. Some other time after having saved it and replaced it with a new DME and then having the "new" DME fail and the old DME work fine again. There is a set of points inside and I think they stick sometimes and then later on come loose and work again. The DME with the 993 part number is the current one for our car to use. Good luck, Bob Blackwell.

Not sure that thats actually good news when the newer ones fail within 2 years. Oh well, I guess I'll just get another to have on stand by.



Thanx for sharing your experiences Bob. Just how many of these things have you ran through?

I'm not familiar with the brand in the pic but if you try an OE relay you may have better results.



I've always replaced mine with dealer DME relays (STRIBEL) and haven't had one fail yet.
