Digital Gauges quit working

[Eddie tee]

HI I Just found this site and have been looking through it and Just love it!! This is my first post , so here I go. MY 1994 Vett "Yellow" has just started to give me a problem in the last couple of weeks. 1st. my analog gauge for the water temp is reading extremly high all the time,:confused I took it to the shop and they replaced the sensor. $225 bucks later and it still is not fixed.:duh So I start using the Digital guages and they worked fine up to this last weekend. Now none of these digital guages are showing a reading in water temp.,voltage,oil presure,oil temp.
Any Help would be very much appreciated>
Thanks

Given that all are not working it sounds more like a dash problem than sensor problem.Could be bad grounds or loose connection somewhere.
There is a proceedure for checkingthrough but you need the Factory Service manual for the diagnostics.
