Check the obvious/simple things first, fuses, grounds under dash and elsewhere. It'd be good if you could create a signature so we can help.



Welcome to TDR land - sorry your first post had to be in the 911 section. However, I'm sure someone will be able to help out.



Best regards.

No ECM on 97. Could be engine speed sensor but more likely ground (wires or connector).



Fuel shut off relay is on drivers side cowl (fire wall) right next to fuel heater relay, this shouldn't have any thing to do with is problem.



As per 96 seervice manual ground 201 is at lower right side of instrument panel,gound 202 is near or on radio. These seem to be the two main grounds there are a couple of others.
