Hello all

My 1990 Civic DX 4 door died all of a sudden while I was driving. It shut off and will not start again.

While waiting for the tow truck to arrive I pulled up the carpet and counted 20 blinks on the ECUs LED. I pulled out my handy Haynes computer manual and noticed that code 20 is Electric load detector: open circuit or ground possible in ECU wiring.

Does anyone have any ideas what I should look for when troubleshooting this? What is the electric load detector and where is it located?

Thanks a lot
