Why Ruofan’s gasoline car can’t start: Cause analysis and solutions
Recently, the problem of Ruofan gasoline cars failing to start has become a hot topic of discussion among car owners. This article combines hot topics and user feedback from the entire network in the past 10 days to conduct a structured analysis of possible causes and solutions to help car owners quickly troubleshoot problems.
1. Statistics of common causes (data from the entire network in the past 10 days)
| Cause classification | specific questions | frequency of occurrence |
|---|---|---|
| battery problem | Battery loss/aging | 38% |
| fuel system | Fuel pump failure/oil line blockage | 25% |
| Ignition system | Damaged spark plug/faulty ignition coil | 18% |
| Start the system | Starter motor failure | 12% |
| other reasons | Anti-theft system lock/ECU failure | 7% |
2. Diagnostic methods for specific problems
1. Troubleshooting battery problems
• Check the instrument panel: If the instrument light dims or flashes significantly when starting, the battery voltage may be insufficient (normally should be ≥12V)
• Power-on test: Use the emergency power supply to power up and start. If it can start, confirm the battery problem.
• Life span judgment: The service life of ordinary lead-acid batteries is usually 2-3 years
2. Fuel system inspection
• Listen to the fuel pump: You should hear the fuel pump running when the key is turned to the ON position (lasts 2-3 seconds)
• Measure oil pressure: Professional maintenance points can detect fuel pressure (refer to the maintenance manual for normal values)
• Observe the exhaust pipe: smell the exhaust pipe to see if there is a gasoline smell after starting it several times.
| Failure performance | Possible reasons | solution |
|---|---|---|
| No response on startup | The battery is completely dead/the circuit is broken | Replace the battery or check the main insurance |
| The starter turns but does not start the car | Fuel system/ignition system failure | Check spark plug flashover |
| Difficulty starting (requires multiple attempts) | Insufficient cylinder pressure/clogged fuel injector | Professional engine maintenance |
3. Top 3 recent frequent problems faced by car owners
1.Difficulty cold starting in winter: The sudden drop in temperature causes the viscosity of the engine oil to increase. It is recommended to replace the low-temperature engine oil (such as 5W-30)
2.Anti-theft system accidentally touched: Continuous incorrect operations on some models will trigger protection and require the remote control key to be unlocked again.
3.Oil quality issues: Adding low-quality gasoline causes the fuel injector to become clogged. It is recommended to use fuel additives regularly.
4. Emergency treatment plan
•Cart start method: For manual transmission models, you can shift the stroller to 2nd gear and release the clutch after reaching 10km/h (pay attention to safety)
•jump start: When using a jumper cable to connect the battery of other vehicles, you need to connect the positive pole first and then the negative pole.
•Professional rescue: If it still cannot be started after several attempts, it is recommended to contact a 4S store or professional maintenance personnel.
5. Suggestions on preventive measures
| Maintenance items | Recommendation cycle | Things to note |
|---|---|---|
| Battery testing | every 6 months | Keep electrodes clean |
| Replace spark plug | 20,000-40,000 kilometers | Model specified in manual |
| Fuel system cleaning | 30,000 kilometers | Use regular additives |
If your Ruofan gasoline vehicle has a starting problem, it is recommended to follow the above steps to troubleshoot it step by step.
