    Electric food
    • Battery
    • A burned-through crossing point
    • Fuse
    Connections with "weight" Supply of fuel
    • Toplivoprovod
    • Fuel filter
    • Fuel pump
    Ignition system
    • Spark plug
    • High-voltage wires
    • Ignition coil
    System of decrease in toxicity of the fulfilled gases
    • System of ventilation of a case
    • Vacuum leak
    • Installation of a corner of an advancing of ignition
    • Frequency of rotation of idling

Malfunctions of MFI system are often caused by bad contacts in sockets of a plait of wires. Therefore check reliability of connection of all sockets.
