just purchased a 1999 Firebird at an auction. Battery was dead when we picked it up and jump started the car. The tach nor speedometer are working. I am not sure if they were working at the before the battery died.
Vss has been replaced.
auction cars, often a BIG mistake. If good, people sell them honesty man to man. Pray it's not a flood car, and remove the dash to see if wiring is bad going to the dash. If not, often a worn out dash circuit board, those cheapies were made in China
