What are the reasons for the Roewe 750 starter motor not responding?
2 Answers
Roewe 750 starter motor not responding reasons are as follows: Severe wear of starter carbon brushes: The symptom during startup is weak starting power. The crankshaft rotation is visibly slow through the belt and pulley. When the wear is extremely severe, the starter cannot drive the crankshaft to rotate at all, only producing an electric current sound. Starter control mechanism failure: In addition to the starter motor, the starter assembly includes an electromagnetic control mechanism. When the control mechanism fails, the small pinion gear cannot engage with the large flywheel gear, preventing the engine from starting. The symptom is that when turning the key to start, only the high-speed rotation sound of the starter is heard without the sound of the engine crankshaft flywheel operating. Starter clutch damage: Generally, the starter operates at a speed of 120r/min, while the engine idles at around 900r/min after starting. The clutch’s function is to prevent the engine from driving the starter in reverse if the driver fails to release the key in time, keeping the small pinion gear and large flywheel gear engaged, which could cause the starter to burn out.
My Roewe 750 also experienced the issue of the starter motor not responding. Start by checking the simplest possibilities first. After parking, the car wouldn't start, and I suspected it might be due to insufficient battery power or loose connections, especially since battery voltage drops quickly as it ages. Try turning on the headlights—if the brightness is normal, the battery is likely fine; otherwise, you'll need to check the battery or charge it. Next, inspect the fuses. The Roewe 750's starting circuit has a dedicated fuse, usually located in the engine compartment's fuse box—if it's blown, replace it. If that's not the issue, the problem might be with the starter motor itself being stuck or having internal circuit damage, or the ignition switch could be faulty. In my case, it turned out to be a corroded relay, and replacing it fixed the problem. Remember, safety first—if the car won't start, don't force it. Call a tow truck to take it to a repair shop to avoid any hazards on the road.
