Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Deciding to post just to see if anyone else has heard of a similar situation. Going to list facts to make read easier 2001 911 turbo manual. Car has a stage 1 tune Driving on highway and car died. Found ground connections on top of the sending unit burnt. Replaced fuel pump, sending unit and replaced ground wire pin and about 1/2” of wiring with 12g wire and oem pin. Car starts and runs for 3 seconds and dies clean Replaced fuel filter and fuel pump relay. All OEM parts from pelican. No change Check DME relay, had DME and immobilizer sent to tuner to bench test and it ran ghost car on bench. I did see voltage drop on start before car died. It seems that the computer is losing handshake and the immobilizer is shutting down after about 6 seconds.( after full charge car ran for 6 sec. Instead of 3) Using AUTEL computer, computer loses connection when the car dies. Put a 10a jumper on DME relay and no change. Tested the engine ground by attaching cable to block and meter on positive while starting the car. Did not see any abnormal change in voltage. Also, all lights in the car seem normal when car dies so I don’t think it’s a total power issue. Does anyone have a wiring diagram for the DME ground section? This is what I have so far, without the wiring diagram I can not really move forward I am able to test other circuits just fine. Clutch and pedal position, fans , fuel pump ect. Please excuse this dry post, typing on phone and short on time.
