Check out my site if you want more info on 3T GTE's. Everything you need to know is there.
There are 3 pressure switches. One is fuel enrichment, one fuel cut and one is for the knock control.
The switches are normally open. So with them both not earthed it is saying that there is an overboost situation as well as a need for a richer mix. This is why the fuel stops.
If you have fuel enrichment only the engine wil keep running just like if you only have fuel cut it will keep running.
Basically you can't have fuel cut (set to about 7.5 psi) without fuel enrichment because its set to about 2 psi.
