Hey guys I got a 91 Ef hatch that was shut off the other day, and now it won't start. Did main relay test and the harness test and both checked out good. I checked them with these following steps - Checking Main Relay, with pics!!! - Honda-Tech Now this car is converted to OBD-1 and everything checks out, including the ignition, but suddenly the main relay wont turn on. Just to add more confusion the car is built and boosted but no wiring has been added except for the Phearable.net OBD-1 jumper harness. The Ecu is a chipped Hand Command ECU. I thought maybe the ecu was the problem so I plugged another one in but the main relay still wont turn on. So I'm lost right now, I am checking grounds and continuity right now but does anyone have any ideas? Thanks in advance.
