BUZZING SOUND FROM INSIDE DASH ,LEFT SIDE,TEMP GAUGE,FUEL GAUGE,OIL GAUGE NOT WORKING,ALSO PARKING BRAKE LIGHT NOT COMING ON WHEN ENGAGING PARKING BRAKE, BUZZING SOUND GOES AWAY WHEN I PUT TURN SIGNAL ON BUT GAUGES AND LIGHT STILL NOT WORKING,

so did not check all fuses first? and IS.
can you be more clear, what works and does not work?
electrics failures, we need all that works to
not told does, car drive day or night.? (A#1purpose)
head lamps
brake lamps
parking
turns
radio works
heater dash blower works on high.

gauge back lamps you meant and are part of PARK. +dimmer.

and what does this mean.

dash lights
you mean the cluster waring lamps are dead
like doors open, CEL, brakes, oil, seats belts., etc, be clear .
we are blind here can not see your dash.

can be all of the above as for when oil pressure spike the sensor is electronic its getting a spike /surge from brake switch ---look for body ground or wire harness problem as to parking brake switch under dash attached to the emergency brake pedal also invest in a repair manual such as chilton or hayes their cheap and offer assistance into problems such as this and step by step repair

Check all cables including those to alternator for corrosion, typically greenish. Dielectric grease is helpful on contacts. New cables may not be necessary but if heavily corroded they aren't terribly expensive.

circuitry behind the gauge panel. you will have to pull the dash to see behind there and track the problem down

If the parking brake light comes on, it would indicate to me that the switch on the parking brake peddle may need adjustment. This would also deactivate the 4x4, you would not want to drive around with the brake on. Not sure about the fan blower and cruise but all are in dash and the dash does have a common ground behind the lower left kick panel. A loose ground connection can cause much havoc.

Do you know that all this stuff was working when it was parked? Lets assume it was. Most of this stuff works with the key on or in the acc. position. You are going to need something to check for voltage. At least a test light better yet, multimeter. The dash lights however, come off the headlight switch. Start by checking for power at the fuse for the gauges it's marked "inst" for instruments it protects all the gauges including the tach and speedo. With the key on you should have power on both sides of the fuse. The antenna won't come up until you get the radio to come on. If you have power at the fuse, Your going to have to start taking the dash apart to see where the "open" in the circuit. If you have no power at the fuse, it comes from the ignition switch, it's down low on the steering column. ( I hope you're skinny)

As for the brakes, since it's been sitting that long I would be pulling the wheels off and looking for a seized caliper.

If your going to do your on work on this car I recommend investing in a good manual, try to find a factory book on ebay. or Craig's list.

This is a way cool car, have fun with it!!!

ther is a micro-switch on the park brake linkage and it is either defective or out of adjustment.

faulty wiring for the lights, and blinkers....

broken gears for the fuel and temp gauge...

just get rid of the damn car, get a Civic of the same year.

I was given a 323 once, unsiezed the rear brakes (the idiot left the thing parked with the e-brake on all winter), then sold it for beer money.

hello this sounds like a bad ground to the gauge cluster first thing to try with the key in the on position tap at gauge area see is there any change if not open dash area were gauges are wiggle to see if they are grounded good into dash grab a test light take end put to the ground on one off the gauges touch other power wire with probe while key is in the on position same for both gauges if no difference reinstall you need to check grounds on both gauges by tracing wires it might be easier if you locate your oil sending unit take the wire off attach alligator clip to wire now touch positive side of batterey if it lights grounds okay trace back to units oilsender,sending unit at gas tank goodluck please rate

check all the fuses first
