1. Overhaul car engine can not be started
1, to identify the cause of the malfunction. Diagnosis engine can not start such failures should
first detect the battery. Need to be clear, the engine can not be started is not lack of battery
power.
2, detection ignition timing. Timing belt obd2 スキャンツール, cause no spark, the engine can
not be started this failure.
3, detection start system. The engine can not start such failures, first set out to do the work is the
the detection engine start system circuit. From the basic composition of the form view, the start
circuit Generally following the most basic part of that battery, start the motor and cables to
connect these components. Of course, in addition, the ignition switch, starter relay or solenoid
coils, there car anti-theft system, etc., also is an important part of the boot the system.
4, to detect the ECU プログラマー quality. Start system does not fault circuit testing to show
that attention should be concentrated the engine Why can not operate on. Generally speaking, it
is the first detection of the ignition system of the engine, which is the easiest one detection work.
In the the early ignition system, you can easily remove the ignition coil, and then use a spark
detector detects spark is normal. Choose spark detector, the detector can be adjusted more
desirable than a fixed design, because it allows you to adjust the detector to a smaller gap, so
that you can know, no spark generated or spark but very weak?
5, the detection of the fuel system. The diagnosis of the fuel system can be divided into two parts:
the fuel supply system of diagnosis and injector circuit diagnosis. The fuel supply system can be
detected by measuring the flow and pressure of the fuel. The best way to measure the fuel flow,
with a load in the fuel supply line detection pipeline.
6, the detection of anti-theft system: vehicle anti-theft system will also have some of the often
overlooked キセノンランプ of the fuel supply system failure. Some car manufacturers in the
data stream of the anti-theft system, including parameter identification. In many models, the
replacement of the anti-theft system module without it the correct initialization process, it will
cause the car not start. There are some cars in certain circumstances, such as when the master
key is lost, the need to replace the multi-function controller to allow the engine to start properly.
