I have a 91 Honda that is automatic it has been having issues
Will not start in the heat it free spins like not compression.
Then the sports light would blind on and off when I tried to start it and would not start if it was blinking. Someone said it was the trans computer replaced it but the weather is cooler now so it was running .
I thought great it was taken care of the problem but the other day driving it loss the spedo,tech and radio all power.
Was told the main computer $550 later it still does not run the light comes on when the door opens so it comes on.
Now I would collect insurance on it but not worth it plus it is all I have to drive.
Can someone please set me in the correct direction to get this figured out.

. Check all under hood and under dash fuses with a test light or multimeter.

. Check for codes.

. Verify that the Check Engine Light comes on for 2 seconds and then goes out, when the ignition switch is turned to ON (Position II).

. Test the alternator. The brushes may have been worn down so far that it caused loss of power.

. Replace the main relay, if the engine does not start when the temperature rises.
