DME relay location
 

I'm new to the Porsche world. I am working on a 85 911 turbo. I am experiancing a crank no start condition. The fuel pump does not turn on. Everything i am seeing on line points to a possible DME relay falure. I can"t seem to locate to relay. This is a gray market car so I'm wondering if anyone could tell me if it has a DME relay to begin with a where it is located if it does.

FP relays (2) are on the front fuse board. Usually red, rearmost positions. FP fuse is #6. There's also an overboost relay on the rear electric panel, yellow, that keeps the pumps from running wnen the overboost switch goes open circuit from too much boost, bad switch or the wire fell off. That relay can suffer cracked solder joints also.

Another fairly common FP failure is the weakening of the clips that hold the FP fuse in place. Good idea to inspect the fuse for snug fit.

The DME relay on a 3.2 is under the driver's seat.
Slide seat to front and back to access the bolt and harness clip.

it's a 930. No DME.

Does one have to unscrew a bolt that goes through the tab or is it just pull out and plugin?
