    Perform the K-Test on the ECM:

    The K-Test: Remove the MAP Sensor connector and turn the ignition switch to ON (Position II). Using a multimeter, check for 5 volts going between the MAP Sensor connector's reference wire (+) and ground. As you look at the connector, this is the socket on the right. Really press the black test lead into a cleaned main ECM ground on the thermostat housing. If the voltage is low, it’s probably indicating ECM failure. Most failed ECMs will record a fraction of a volt. To me, the K-Test is simple, elegant, and accurate.

    People are their own worst enemies. Try and help someone and look what happens. Go figure. He previously tagged on to someone elses' posting, kitch428, that had a 1990 Honda Civic Hatchback.
