Hello everyone,

I'm going to be getting my 1998 C2S out of storage soon, and I would like to pull the DME relay prior to starting my car. I don't know where it is located...I'm assuming it is in the engine compartment somewhere? I heard that it was a good idea to pull the DME prior to the first start of the season to circulate the oil. I was also told that it is a good idea to keep a spare DME in the glovebox....I bought one, but it would not do me any good if I didn't know how/where the original DME is.

Your help is much appreciated!

I found the DME Relay last night. It is located in the fuse/relay box in the trunk...on the passenger side of the car. I have multiple #53 relays in the box...I would say there is at least four marked #53, so I looked a little more and discovered one that had DME printed on it. I pulled the DME relay and cranked over the engine of my car until I saw the oil pressure rise and stabilize around 20psi (this took about 5-10 seconds). Now that I know I have circulated the oil around the engine and I have oil pressure, I put the DME relay back in and fired up my car! She started right up...no noise from lack of oil in the valve train, no puffs of smoke out the exhaust! I wish I had known about this trick years ago!

Never really heard about pulling the DME relay...but it sounds like a good idea. Any negatives to doing this? I'm going to be pulling my 993T out of storage in a month or so and of course thinking about stuff just like this.

I realize this is an old post but pulling the DME relay is good to do after log periods of storage or even after you change the oil. I turn the engine over until I get at least 2 bar and then put the relay back in and fire it up. Works well.
