Why can't the Roewe RX5 start despite having electricity?

[Olivia]

Here are the reasons why the Roewe RX5 may have electricity but cannot start: 1. Circuit or electronic failure: The occurrence is very sudden, with no warning signs. Circuit failures include: blown fuse, open circuit in the high-voltage coil, open circuit in the low-voltage circuit, detached central ignition wire, leaking distributor head, or damaged spark plug. Electronic failure mainly refers to the central computer control board losing function. 2. Fuel system failure: Stalling caused by fuel system issues often comes with symptoms like weak engine power and the accelerator pedal feeling like stepping on cotton. Possible fuel system failure locations include: malfunctioning fuel pump, blocked fuel line, clogged fuel filter, failed carburetor, damaged injector, etc. Sometimes, the fuel tank may be empty without the owner realizing it.

I've driven the Roewe RX5 for many years and have encountered the embarrassing situation of having power but the car not starting. The most common issue is battery problems—although the dashboard shows power, the voltage is too low to turn the starter, or the terminals are corroded or loose, causing poor contact. Starter motor failure can also occur, where you only hear a clicking sound or no response at all when turning the key. Additionally, if the ignition system, such as spark plugs, is severely aged or carbon-fouled, it can't ignite the air-fuel mixture; if the fuel pump is damaged or not supplying fuel, the engine can't draw in fuel. I've also experienced the anti-theft system mistakenly locking, possibly due to a weak key battery or signal interference. When this happens, don't force it—first check if the battery terminals are tight and test if the voltage is below 12 volts. If that doesn't work, have it towed to a repair shop to avoid risks on the road. Such failures often stem from neglecting regular maintenance, so it's recommended to inspect related components every six months—safety first.

I bought a Roewe RX5 less than a year ago, and it's really frustrating when a new car has electricity but won't start. I encountered this issue during a trip: the lights were on, indicating there was power, but turning the key didn't get the engine to respond at all. Later, a friend reminded me that the fuel pump might be faulty, causing no fuel supply during startup—listen for any humming sound in the engine bay or check if the throttle is stuck and unresponsive. Another common issue is excessive carbon buildup on the spark plugs or failure to ignite, especially after long drives. Loose battery connections can also lead to false power readings, so it's worth checking the terminals. Now, I regularly inspect these components to avoid embarrassing situations in urgent moments, as delays could lead to more problems, like completely draining the battery. This small lesson taught me not to rely solely on the dashboard—learning some car knowledge is practical and helps quickly decide whether to call for roadside assistance.

I always enjoy tinkering with my car. There are quite a few possible reasons why a Roewe RX5 might have power but fail to start. The simplest could be a weak battery—it shows power but struggles to start; if a multimeter reads below 11 volts, it's time to recharge. Other issues might include a faulty starter, such as a stuck solenoid switch or worn-out carbon brushes; problems with the ignition coil failing to produce sparks; or a dirty throttle body causing insufficient air intake and an imbalanced air-fuel mixture. A clogged fuel filter can also lead to poor fuel supply, causing the engine to stall immediately after starting. When checking, observe if the key triggers the anti-theft light—if it stays on, it indicates a weak signal. Keeping a basic toolbox handy allows you to troubleshoot minor issues yourself, saving a trip to the shop. However, for complex problems like ECU faults, it's best to leave it to professionals to avoid causing further damage to the car.
