ECU is in the front passenger footwell, high on the right. Its clear that you have no manuals, but you'll need one if you want to do more than stare at it. Unless you install a battery with the polarity reversed, which does destroy the ECU, its is not likely to be the problem on these cars. If its "dead", and the battery is good, the lights come one, the strater turns the motor over, but no fuel no spark then check the fuses in the box on the upper left of the driver's footwell and the ones in the box in the engine compartment in front of the left front wheel. If it isn't totally dead, get the Hayes manual at the local ato parts store and read how to get the ECU codes w/o a tool and go from there.

90-91, its under the dash, on the left side of the steering wheel. The ECU is the one farther towards the door. Just a side note if you need it, abs controller is under the passenger seat.

Temp gauge wont stop reading hot and dash lights flicker

90% of the time the reason for this is because there are air bubbles in the cooling system. You just have to bleed the system and you will be fine
