A mileage of about 103,000 km in 2009 Dongfeng Honda CRV 2.4L car. The owner Description: This car hot car starts normally, cold start problems.

         Maintenance Summary: This car is due to poor quality fuel filters, use in the process of relief C110 code reader phenomenon, resulting in a period of time after the start when parked fuel oil pressure is too low, resulting in difficulty in starting the vehicle failure occurs.

        Cause there are a lot of vehicles difficult to start, for the maintenance of such failure to pay attention to the following points.

        1. To reproduce the symptom. This allows us to determine the cause of the fault is probably generated, in order to properly lock the scope of the inspection.

        2. Check the easy things first, after the first electric machine. This avoids spent a lot of effort, wasted a lot of time before a very simple to detect glitches.

        3. To be good at communicating with the owners. This helps troubleshoot, detours, which can save time, as soon as possible to identify the point of failure.

        4. Equipment and diagnostic use a combination of ideas. Only good proper use of equipment, in order to conclude that there is no fault check items; only diligent in thinking, in order to have a clear idea of ​​the diagnosis.

         Troubleshooting: After receiving the car, the first vehicle to start, and found no abnormalities. Parked about 30min after turning the ignition key, 7 ~ 8s to start the vehicle on fire. After starting the engine in normal operation, road test, normal. HDS use vehicle testing, no fault codes. View the data stream can be concluded that this car temperature sensor is normal, nothing to start with the water temperature sensor fault difficulties. Check the EGR valve, normal. Multimeter battery voltage detection: the battery voltage is 12.1 V when parking; start operation SmartPRO 5000U-PLUS programmer minimum battery voltage 11.3V; after starting the vehicle battery voltage is 14.2V. It can be concluded that the use of the battery in good condition, independent of the difficulties with the battery to start the vehicle. Check the throttle, no dirt; check the pipeline, no leaks; hydraulic tests were normal.

        Is the nozzle blocked? However, after viewing the car well maintained. Is this car had been in an accident or were dismantling the nozzle? Through communication with the owners, I learned some time ago, this car is in the "roadside repair shop" did not start until maintenance difficult phenomenon occurred. When the maintenance carried out throttle cleaning, replace the oil and fuel filter cleaning. This car collision did not occur, nor conducted injector disassembly.

        So what would cause the vehicle to start trouble? Is fuel filter are different.
