Have you checked your alternator regulator? If your battery isn't holding a charge, this could be the issue.

yes is ok,but don't have ground out of pin 36 on the ECU

[Bill Verburg]

'94 993 uses Motronic 2.10.1 which wants a ground at pin 36

I'd start by finding the break in the wire that prevent that.

The most common issues are related to the DME relay or the immobilizer
