1) After installing the burglar-proof device, it is difficult to start the non-hot car even if the net starts up three times or more, sometimes even if the battery is exhausted. It is found that the oil pressure can be maintained within a certain period of time after the normal oil pressure is extinguished. It is not a circuit problem, but it may be a circuit problem. Read the fault code, 14 or the ignition acknowledgement signal is out of order. The reason is that the ECM outputs a 4-angle-of-fire trigger signal "the terminal controls the ignitor but the IGF terminal does not send the ignition confirmation signal to the ECM." Inspection found that the ignition coil power line was broken, and installed burglar-proof control wire connected to the engine oil pressure indicator switch. In this way, when starting, the oil pressure low burglar breaker control line grounding, breaking off the breaker corrosion point caused the ignition coil power interruption igniter also can not send ignition confirmation signal, so the ECM order to stop fuel injection, become difficult to start the barrier. Remove the breaker of the stolen device and replace the original circuit. 2) a car is still normal due to its serious engine oil and idling. Inspection sub-inspection found that the cylinder head was removed to check the valve closure re-examination run to remove the cylinder head and oil pan, the cylinder liner, piston and valve assembly inspection to find that the fourth too thin engine work badly; high-speed fuel supply increased when the fourth method for cracks: adhesive bonding
