You are probably in the end stage of its life. Prepare for an imminent failure. Mine squealed for a few months off and on before it gave it up. Following the funeral I replaced it. If you are handy and patient, you can replace it, but have all the parts ordered beforehand. I got mine from IPDUSA.com and was happy with the outcome.

I don't think there is a rollover switch on a '91 wagon.
The ECU supplies ground to the fuel pump relay for only about a second and a half if there is no ignition pulse. This is what shuts off the fuel pump in the event of an accident. The transistor in the ECU that provides this ground signal fails after a couple of decades. Repairing it is not a do-it-yourself operation but there are rebuilt ECUs available from multiple sources. Be sure to get an ECU that is compatible with your vehicle configuration.
timimg belts usually don't make noise, they break and the motor stops!! The noise could be coming from a bad water pump, powersteering pump, air compresser, alternater, leaky exhaust, leaky vacume lines. Check them out. Or, I don't know the condition of the engin. Has it been neglected and are the bearing going? More history would be helpful.
