Checked and the PATS led doesn't come on at all

Also, I tried disconnecting the battery for a while, reconnected it and the car started on the first turn of the key ... drove a few hundred yards, died on me and wouldn't start again, exactly as before


I found this on a PATS info page for mk3 fiestas:

The engine does not start and LED remains off. 1. Check PATS system fuses 2. If alarm is fitted check if LED functions for alarm: if not check cigar lighter fuse (also used for LED) 3. If not go to main dealer


Could it really be something as simple as a fuse?

Nearest place I can get a fuse from to check is ten miles away which makes it a difficult when my car won't start
