There should be ****s to turn on the motors to rotate the head lights manually. If they open up again later, the motors are good. They rarely fail, and two will not likely fail at the same time. There is a relay block under the dash near the steering column. I've replaced them but never tried to take one apart to see if there was something I could repair. That is more likely to be the cause of the problem.
Try tapping on the tach while the engine is running. If the needle jumps a little, suspect the laminate has shifted and the needle is rubbing on it. You can trim the hole with a small hobby knife. It's too messy to try to move the laminate.
Not sure about the odometer. There should be no speedometer cable on 1990 models. If the speedometer is working, the speed sensor and Body Computer are too. That would leave the stepper motor and the circuitry in the cluster that runs the odometer.
For the gas smell, start by looking in front of the right rear wheel for wetness. Sometimes the hose clamps rust off the hoses for the filter. If the hoses are crimped to the steel lines, there is a repair kit that includes four fittings and clamps. You only use two fittings. Two are straight and two are curved. Use the ones like the originals. Look for other places along the right frame rail for signs of a steel line rusted through. Also check the short rubber hoses that go from the body to the engine near the right strut tower. If they are leaking, you can use bulk fuel hose but get fuel injection hose, not the standard stuff used with carbureted cars. Throttle body systems run around 15 psi, three time higher than cars with carburetors. Multi-point systems can easily go over 50 psi.
