P0001 Diagnostic Code for 1998 Mazda 626 LX: Causes and Fixes for Starting Issues

Model: 1998 626 LX Fault Code: P0001 Posted: 2011-01-02 11:38

My 1998 Mazda 626 LX (6-cylinder) won't start — it cranks over but misfires and fails to ignite. Using an OBD-II code reader, I've identified a P0001 fault code: 'Fuel Volume Regulator Control Circuit Open'. The local parts store is unfamiliar with this issue, and online searches suggest that the meaning of P0001 can vary by manufacturer. Can anyone confirm what this component does on a 1998 Mazda 626 LX and how to diagnose or repair it?
