e to match the best ponents, fuel injection time and ignition time. РSecond, Electronic Control Engine Troubleshooting and Maintenance Methods Р Engine Electronic Control Fuel Injection System as long as there is oil has electricity, fuel injection time and ignition time is accurate, the engine can be launched by the fire. If there is a fault in the starter motor, the engine may be difficult to start, idle, such as instability or accelerated undesirable phenomenon, it is a mon fault, probably due to the fuel pump does not pump fuel pump oil or lack of fuel injector , cold-start circuit to plug the nozzle and, bad pensation system, water temperature sensors, air flow meter and control the work of non-performing circuit caused bad. Below a few examples of maintenance for a specific analysis:
