Verification system of injection MFI

If MFI components (sensors, ECM, fuel injectors, etc.) fail, broken fuel supply to the cylinders of the engine at different operating conditions, resulting in the following situations:

• the engine is hard to start or not start:
• the engine is idling is unstable;
• the engine in all modes is unstable.

If you have any of the above situations, first of all follow the normal diagnostic (ignition, adjust the engine, etc.), and then check the components of the MFI.
