    Bad ECM or main relay. Perform the K-Test on the ECM.

    What is a k test for prelude 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.

    If the CEL comes on and goes out after 2 seconds, when the ignition switch is turned to ON (Position II), then replace the Ignition Control Module and coil:
