Why can't the Roewe RX5 start even though it has electricity?

Roewe RX5 can't start even though it has electricity due to circuit faults, electronic faults, or fuel system faults. Additional Information: Roewe RX5: The Roewe RX5 is an internet SUV launched by SAIC Roewe in 2016. Roewe RX5's Engine: The vehicle adopts the 'Blue Core' high-efficiency power technology, equipped with 2.0T and 1.5T in-cylinder direct injection turbocharged engines. Specifically, the 2.0T engine has a maximum power of 220 horsepower and a peak torque of 350 Nm, with a minimum combined fuel consumption of 8.1L per 100 km; the 1.5T engine has a maximum power of 169 horsepower and a peak torque of 250 Nm, with a combined fuel consumption of only 6.8L per 100 km. Additionally, the Roewe RX5 features Porsche-tuned chassis, GKN intelligent all-wheel-drive system sourced from Land Rover, fully independent suspension system, and a four-way high-speed CANBUS system bus, comprehensively enhancing the driving and riding quality.

My Roewe RX5 recently encountered the same issue. The dashboard lights were on indicating power in the car, but the vehicle just wouldn't start when I tried to ignite it. At first, I thought the battery was dead, but after checking with a multimeter and finding the voltage normal, I ruled out battery problems. Then I inspected the starter motor and suspected possible poor relay contact or ignition switch aging causing connection issues. Further investigation revealed that worn-out spark plugs could also cause ignition failure - replacing them with new ones solved the problem. Additionally, pay attention to the fuel system; if the fuel pump or filter is clogged and can't supply fuel properly, the engine won't start. The mechanic reminded me during repairs that when the crankshaft position sensor fails, the ECU won't receive signals and the car won't start either. In summary, don't panic when facing such situations. Start troubleshooting from simpler components first, and if all else fails, take it to a professional repair shop promptly to avoid travel disruptions.

I was driving my Roewe RX5 when it suddenly wouldn't start, which gave me quite a scare. The dashboard had power but there was no response when trying to ignite. I tried troubleshooting myself, and it might be due to a fuel pump issue causing insufficient fuel supply, or excessive carbon buildup on the spark plugs preventing ignition. Another time I encountered a similar situation, it was because the starter motor was jammed, and replacing a small part fixed it. Loose or oxidized wiring connections causing poor contact are also common, especially in older cars. A dirty air filter affecting air intake can also lead to starting difficulties. I recommend checking these vulnerable parts first like I did to save time and money. Regular maintenance can prevent major repairs and reduce the hassle of such minor faults.

My Roewe RX5 has occasionally encountered a starting failure issue after prolonged use, where the battery shows sufficient charge but the engine fails to start. Based on my experience, the root causes primarily lie in the starting system: first, the starter motor gear may be stuck or worn out due to aging; second, there could be a response delay in the electronic module of the ignition switch; third, fuel system issues such as insufficient fuel pump pressure or a clogged fuel filter causing supply interruption. A faulty crankshaft sensor can also frequently cause trouble as the ECU fails to coordinate engine operation. The solution involves systematic troubleshooting—for example, removing the spark plugs to check ignition status or scanning for error codes with a diagnostic tool. Don’t rush or cut corners; ensure safety before any DIY attempts and replace necessary components promptly, otherwise a roadside breakdown will be far more troublesome.
