Loose DME connection

Recommended Posts

I have an 1987 911 Carrera and for months the car will randomly fail to start or will quit on the road. I have replaced the distributor cap, rotor, coil, fuel pump and DME relay, yet the problem persists. I believe the problem is being caused by a poor contact at the DME and the DME connector cable. If the car fails to start I can wiggle the connector and get the car started. I have cleaned the contacts and used dielectric grease on the connector to no avail. Does anyone have an idea how to improve the connection at the DME?. I was thinking of using long cable ties to hold the connector more firmly

That is being done at this very moment, If the pins and sockets are in good shape I am at a loss as to the next step. I have owned this car since it was new and have never had a problem until this year. Now it is completely unreliable.

I experienced the same issues with my '86. Turned out to be a poor plug connection for the reference sensor located on the bell housing at about 2 o'clock on the drivers side. Sensor and plug may need some cleaning.

I believe that you also have a ground strap from the trani to the chassis on the passenger side.

Good luck.

I finally resolved the Issue. It was a bad DME. The DME would fail at random,, but the time between failures was decreasing. When I took the DME to a Porsche rebuilder in South Miami he tested the DME and it failed every few seconds on his test equipment. I bought a rebuilt DME from him for less than $400, installed it and all problems were solved
