yeah it should turn on, light up or something when you turn the key to on.... id pull the cluster out, see if there is a bulb or not. if there isnt (which i believe there isnt) put one in, turn it on and see if you can pull a code. hopefully that works out for ya and you can pull a code.

have you tried taking the plugs out and letting the moisture evaporate from the cylinders? if it isnt warm in indy right now just heat gun 'em....
