need help on my 1990 eagle talon awd turbo cluster..!

[red_talon]

Ever since I bought the car, I can never solve the problem of the cluster..
Everything works Except the Temp gauge and the Fuel gauge. The Temp gauge reads to hot in about 3 mins after the car is start. the fuel gauge goes right to full automatically.
My car is a 1990 Eagle Talon TSI AWD Turbo.

Heres what I have done....
-replace the temp sensor( bought a new one ) the wire from the sensor was good..
-check the fuel pump..it was good.
-bought another 1990 Eagle Talon turbo ecu, swap it but no luck
-bought another 1990 Eagle Talon turbo gauge, also swap it, no luck
-replace the individual temp and fuel gauge, fail...

any more ideas to get the cluster working properly?
any help would be greatly appreciated!

Sounds to me like your ground wire is missing off the cluster.
