    1992 honda accord ex at control module?
    I have a 1992 honda accord that's not cranking I found that the fuel injectors are not pulsing also I found that the at control module is burt next to the ecm is it possible that the at module is stoping the ecm from working the fuel injectors?

    Very possible. 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.

    I think you will find they are both toast.
