tach and temp gauge
ive recently picked up an 89 GXL and i havent driven it that much, but the whole time ive been driving it the temperature gauge isnt working and now the last few times ive switched on the car my tach has stopped working... i dont drive the car much because im about to replace the throttle body but i was wondering if anyone knew if it was just a wiring problem or what else could be wrong with it?

If you don't Know,Don't Post..Please!..the area that you are going to be looking at is the Two wires that are Under the Oil Filter.There are connectors there for BOTH the Oil and the temp.If they are Off then you Found the problem...Oh Edit!..the Tach runs off the Trailing Coil,so Check the Plug wires,the Spark plugs and also the coils wires themselves.

Key ON. Have someone hold the water themperature connector to gnd. Like the block. Only for three or four seconds at most. As THEY hold it agaiinst the block (metal to metal), the temp gauge rises. Don't let it peg out on the top.
Then start the engine and see if the tach is working or not. MaKe sure the battery is fully charged or the ECU MIGHT put the TRAIL coil into a fail safe mode and it won't cause the tach to work.
Neither item is related to the other unless the connectors inbetween the combination meter and them is/are open.
