I Have power going to the unit, I did replace the unit, also still no fuel speed or temp Readings[:@]

 

Mike,

I have the same issue with a 91 Grand Caravan SE. Reading the forums, they talk about bad solder on the master circuit board. I re-soldered the board and when I put it back together the gauges came on for a moment and then they were gone.

If the van sits for a while, the same thing occurs. It's almost like it's overloading a circuit.

Id love to know if anyone else has solved this issie.

Jeff
