[944TurboRacer]

I had a "warm" no start problem with my 944 turbo. The car would always start cold. But if I drove a short distance and shut the car off, there was a good chance it wouldn't start again. If I let it cool completely, the car would start up fine.

I was able to confirm that I had no spark when the car wouldn't start and that the fuel system was working fine.

Ultimately I discovered that the DME unit was the culprit. I found three broken solder joints on one of the DME power transistors. (There are three of these power transistors mounted to heat sinks along the inside wall of the DME unit). Once I resoldered these joints I have never had a "warm" start problem again.

Do an internet search of this problem. There is information out there and photos to assist in this repair.
