Hi Solution1. I have the same problem on my 94 Probe, I don't have a handbook for my car, are you able to tell me where the fuse is located that needs replacing?
SOURCE: airbag dash light flashing code 51
Common fault on FORD
Usually due to a poor connection in the YELLOW PLASTIC CONNECTOR underneath the passenger seat.
Just push it together properly and it should clear the AirBag fault

That code is for the Evaporative Emissions. It could be a bad Evaporative Emissions Canister Valve or just a bad vacuum line or my granddaughter's 1997 Ford Escort had that code and her gas cap was NOT on. Now when you figure out what one it is disconnect the battery for 10 minutes to reset the computer.
