    1990 Chevy truck
    My truck will start, after it has been running and the engine gets warm, it will not restart unless I pour gas in the carb, I have tested all the circiots in the module and the ignition module to be sure it is all grounded. I have replaced the ECM. Any ideas?

    . Check/replace the Engine Coolant Temperature (ECT) Sensor, which affects fuel injector pulse width. The ECT Sensor is a temperature dependent resistor (thermistor), whose resistance decreases as the engine coolant temperature increases. It provides a richer mixture when cold, leaner mixture when hot.

    . Install a new Ignition Control Module (ICM), if it has not been replaced in 120,000 miles or 10 years, whichever comes first.
