    M111 cold start issue

    I don't think ECU has a option to get live fuel time data, its 1994, it has 16-pin, code reading is got by a blink code reader, it doesn't have an OBD2 maybe its OBD1 or not OBD.... I don't think there's a problem in the fuel pressure, due to I have changed the fuel pump and the fuel injectors.
