my speedo is not working. I changed the speed sensor and the guage cluster andd it still doesnt work!!! what do you think the problem could be????

Bad wiring between the two? Seriously, if you've changed the gauge cluster and the speed sensor, thats about all thats left. IIRC the signal goes from the speed sensor to the cruise ECU to the gauge cluster (those two might be swapped, can't remember) and then finally to the engine ECU (at least on the 7a). I doubt anything other than wiring would keep it from working.

OK, the chilton's book on our car gives instructions on how to diagnose a problem using the abs light. When i turn on my ignition, the ABS light does not come on, I changed the bulb and still doesnt come on. So, it has to be a fuse. Does anyone know where this fuse is located?? And where the wires are located from the speed sensor and the ECU?

Ah, I figured you already checked all the fuses. There is a bank of fuses under the dash on the left side by the hood release, and another under the hood on the left side (drivers side). Check all those first. If you don't find anything there, make sure the gauge cluster is plugged in properly and securely.

You people really have to be more specific if you want to diagnose things like this. If other stuff doesn't work, say so!

try replacing the speedo cable too, i have the same problem. getting it all done next week.

lol we 91s dont have all the technical little electronic gizmos. >>
