TRICKY SPEEDOMETER PROBLEM CAUSING BLOOD IN STOOL
IVE DONE EVERYTHING TO GET THIS SPEEDOMETER TO WORK EVEN JUST SWITCH ONCE FOR ME BUT I GET NOTHING. IVE CHANGED THE VSS, 4 WAY BUFFER BOX, GAUGES (3 TIMES). SOMEONE TOLD ME IT MIGHT HAVE SOMETHING TO DO WITH THE CRUISE CONTROL THAT I REMOVED. ANYONES THOUGHTS ARE VERY APPRECIATED. IM TRYING TO SELL THIS CAR AND CANT CAUSE OF THIS PROBLEM. I ALSO HAVE CARBED THIS CAR AND REMOVED THE COMPUTER.

What kind of trans is it and what year? is it a cable speedo or an electric?
There is a VSS signal that goes to the cruise control but it wouldn't effect the speedo by removing it.

it might be the speedo gear if mechanical that is stripped and if its electronic might be worn out to read.

is it the stock gauges? Did you change anything before it stopped working? Are the grounds good?
