Question by -paul posted 6 months 2 weeks ago in Mazda

set codes 02 and 25, crank no start. no spark and no fuel pump sound (pump runs with a jumper installed in diagnostics box only) new distributer and coil now installed with no change. Owner lost all ignition/fuel pump suddenly while driving on interstate. What would cause this and how to troubleshoot, thanks.
