Arthur,
For future reference, can we determine what caused the OVP to burn out (& the fuse not blowing).

I know you are probably saying I think to much again, but I would just like to understand the sequence of events that triggered this. Im assuming that the OVP relay was thrown by the ECU due to dropping fuel pressure.

Which sensor(s) monitors the fuel pressure?
I never got a Check Engine light. Was a code ever stored? Where, SRS system?
Is there a writeup thread here somewhere that decribes (at a high level) the sequence of events during startup?
