Question about 1993 Honda Civic 4 Door
I have a 1993 honda civic, it turns over but does not fire up. I am told there is no spark and that's why it does not work.
When it's hot inside your car it causes a solder joint on a little circuit board in your Main/Fuel Relay to loose contact. The MAIN RELAY is up above your gas pedal near the cruise control computer. Almost directly behind the dash vent. It will be a gray or black box with a plug of wires connected to it. Use a 10mm socket (with extensions to reach). Bring it into view and tap the Relay, "Plastic Box", while someone tries to start the car. If you can bring it down into better view you can tap it and start the car if you're flexible.
TO FIX THE PROBLEM: Don't buy a new one, just pry the cover off of it with a flat head screwdriver and look close where all the sharp pins are sticking up on the board to find the broken solder connection(s). Heat the faulty pin with a soldering iron until the solder puddles around it and your good to go. The crack in the solder will be smaller than a human hair, look close & wiggle it and you'll see the loose connection. There is usually no need to add solder, what is there is enough, it just needs melted again. Works every time on the Accord, Prelude, Civic and Integra.
