93 ford escort

my car stopped starting. when you turn the key i hear a buzzing noise from dash, but nothing else. tried replacing ignition switch, no result. removed starter had it tested, passed. checked battery, passed. dont know what to try next. any ideas would be appreciated.

I’d look at the stater relay

Is the buzzing sound the normal buzzing that occurs whenever the key is on and the engine is not running? Or is the buzzing ONLY occurring when the key is turned to the START position? Possibly you have a problem with the neutral start switch or clutch switch.

Don’t forget the battery cables. Are they clean, capable of carrying a few hundred amps?
