86 porsche 944, starts n runs, while driving at higher rpms, car cuts right off, i start it back up n it runs funky, now last time it did it i pulled dme relay, and puty it right back in and the car ran...


I would buy a used one if you can (dme chip). Have you cleaned the fuel injectors? one could be faulty and could be a coincidence about the car working better after taking the relay out and putting back in. could be a bad cpu also. would love to hear what happened if you get it fixed. good luck

CHECK ENGINE LIGHT ON, WHAT IS DME CONTROL MODULE


Digital Motor Electronics (DME) is a microprocessor-based system that controls the ignition, the fuel injection, the oxygen sensor and numerous ancillary functions. DME provides raw data to an on-board computer that uses an alphanumeric display to provide you with information such as the average fuel consumption, the distance you can still cover with fuel in the tank, an average speed, outside temperature and more.
In the industry, DME is often referred to as the Engine Control Unit (ECU), under the heading of Electronic Engine Management Systems.
DME operates by continually monitoring such factors as engine temperature, speed, intake airflow, exhaust gas composition, and even the altitude. DME then literally fine-tunes the engine hundreds of times a second to provide maximum performance and efficiency. DME has a fail-safe program in the event of certain electrical faults. Current DME versions also have on-board diagnostics (OBD).

The 1998 Boxster location is in the rear trunk space on the left side on the firewall under the carpet.

Car wont start .


You will not be able to hear the fuel pump on that model. First you have to determine if you get fuel and have spark. If it is a fuel problem, replace the DME relay first. Very common. They act up and fail without warning. Part is cheap and located in the fuse box. Next would be the fuel pump.
If it is spark related it may be the Flywheel Reference Sensors. There are two and the cost about $100 each.

Good Luck.
