How to Solve the Problem of Buick Excelle Not Starting and Engine Malfunction Light On?
3 Answers
Check the water temperature gauge and oil pressure warning light. If the water temperature gauge and oil pressure warning light are not alarming, the car can still be driven. At this time, be sure to control the speed and drive to the maintenance station for inspection in time. If the water temperature is too high or the oil pressure warning light is on, and you clearly feel that the vehicle has a malfunction, you should stop immediately and call for rescue. The sensor circuit on the engine is flooded, causing signal transmission distortion. You can drive the vehicle to a maintenance facility for inspection.
That time my Buick Excelle wouldn't start and the engine warning light came on, it was really frustrating. I remember while waiting for roadside assistance, I first tried checking the battery: seeing if the lights were dim or if the horn sounded. If there was no sound, it might have been a dead battery, so I tried getting a friend to help with a jump start. If the light was still on, definitely don't force ignition—it could be the anti-theft system locking or the fuel pump failing. In my case, it was a sensor malfunction, and the mechanic replaced the part. I recommend avoiding random circuit modifications and getting the electrical system checked during maintenance to avoid last-minute failures. Safety first—if this happens, don't panic, just call a professional mechanic to check it out as soon as possible.
As a car enthusiast, I have some knowledge about the Buick Excelle's system. If the car won't start and the malfunction indicator light is on, it's mostly because the ECU has detected an abnormality, such as an oxygen sensor issue or a clogged fuel injector. I once used an OBD scanner to read the trouble code, which showed P0171 indicating a lean fuel mixture. Try disconnecting the battery for a few minutes to reset the system; sometimes this can provide a temporary fix. But don't rely on this trick too much, as a common issue is aging ignition coils. Regular fuel system cleaning can help prevent problems. Pay attention to changes in fuel consumption while driving, as early detection and treatment of abnormalities can avoid greater losses.
