Never trust Morgan fuse box schematics.

Here are two photos of the fuse box:

After removing fuse 1 of fuse block B (first fuse on the left with 7.5A in the lower fuse block) and reinserting it (ignition was off), the engine started again without any problems. The fuse is described as "ECU/IMMOBILISER". I do not assume that this increased the sensitivity but rather that a reset was triggered. I don't know how the immobilizer works and if that is a possible explanation.
