when i first got my car, i got a mo-kan-ick to look it over. the gas gauge didn't work. he told me the sending unit was ok and the gauge was bad. i ordered one from classic ind. and low and behold after 10 months the thing shows up at my door today. (with no notice from classic, so if you ever have anything on backorder and turns out you don't want it be sure and cancel).
anyway, i took the console apart (69) and see that the gauge is not hooked up, so i hook up the old gauge and it goes to way past full. the gauge has the plug on clip with the 2 pinkish wires on one side and the green wire on the other. it also has a blue wire and 2 brown on a screw terminal. is it wiring problem, bad ground or sending unit? is the gauge probably ok? i haven't tried the new one yet, plan to return it if i can find out for sure that's not the problem before i install it.
i checked the archives and i tried:
1. unplug the lead in the trunk in the center of your harness, this should allow your needle to return to E, if not your wires are not in order.
2. an open circuit (ie - unplugging the harness in the trunk)...will act like FULL resistance and will send the needle to the far right (over Full).
If you unplug the connector and jump the sending wire (from the gauge)to ground...(No resistance) it should go to E.
3. Use a jump wire to test have some one watch the gauge as you jump the tank to a clean ground. i also tried grounded at the sending unit.
every time it stayed on full.

says: Locate the fuel sender feed wire near the fuel tank. You're looking for a single tan colored wire. With the tan wire disconnected at the fuel tank, the fuel gauge should read past full with the ignition on. Wait a few moments as some fuel gauges take a long time to respond. Touch the tan wire from the body to any convenient ground and the gauge should read empty. If not, you have a wiring problem or a bad gauge.
so what's up??
i also had to sort of readjust my oil pressure gauge due to bumping it around to get at the fuel gauge (when am i going to learn if i want something done right - get someone else to do it, i'm pretty good at car stereo and new installation, but running down these old elec. problems seem to give me trouble). is there an easy way to do this or just trail and error? i had to adjust the spring and the thing holding the needle in case you have no clue what i am talking about.
it's nice having a way full tank all the time with the gas prices the way they are, but i'd like to get it fixed. help!!!
