The reasons why the Buick LaCrosse takes a long time to start are: 1. The ambient temperature is too low; 2. The battery is dead or damaged; 3. The starter motor is faulty; 4. Fuel injector issues; 5. Engine oil viscosity problems; 6. Incorrect valve clearance; 7. Smoke limiter solenoid valve problems; 8. Insufficient fuel leading to inability to draw fuel or issues with fuel quality and fuel supply lines; 9. Fuel injection pump problems; 10. Stuck fuel injection pump regulating rack. Taking the 2021 Buick LaCrosse as an example, its body dimensions are: length 5026mm, width 1866mm, height 1459mm, wheelbase 2905mm, and fuel tank capacity 55l.

I've had similar issues with my LaCrosse. The car cranks very slowly when starting, sometimes taking several seconds to successfully ignite. I've thought about the possible reasons myself—it might be due to an aging battery or insufficient power, especially in cold winter weather. Last time I encountered this problem, a check-up revealed some carbon buildup on the spark plugs, and replacing them made a big difference. Additionally, insufficient fuel pump pressure can also cause slow starts, such as from clogged fuel lines or a dirty filter. Pay attention to regular maintenance, don't slack on oil changes, and the engine will run more smoothly. Now my car runs much better. I suggest you also try checking these small areas, and if that doesn't work, visit a proper repair shop—safety first. That's enough length.
