What are the reasons for the car not accelerating after starting?
2 Answers
Reasons for the car not accelerating after starting: 1. If it only happens briefly during ignition, it may be due to severe engine carbon deposits, where the fuel is absorbed by impurities, making it feel like no fuel is being added, and ignition may also be difficult; 2. If the issue persists, it could be due to excessive gum deposits blocking the fuel lines or fuel injectors, or a malfunctioning fuel pump. Severe cases may require cleaning, and the use of fuel additives to help dissolve fuel gum and clean the fuel lines. When the car engine is not functioning properly and the self-diagnostic system does not output any fault codes, it is necessary to rely on the operator's inspection and judgment to determine the nature and location of the fault.
I've encountered the issue of the car not accelerating after starting several times, with common causes being problems in the fuel system. For instance, a faulty fuel pump that can't pump fuel, or a clogged fuel line, like a filter accumulating too much debris blocking the fuel flow, naturally preventing the engine from getting fuel and thus not accelerating. Dirty fuel injectors that can't spray fuel properly can also cause this. Electronic components often play tricks too, such as malfunctioning throttle position sensors or accelerator pedal sensors; if the computer doesn't receive signals, it won't allow acceleration. Also, check for insufficient air supply—a clogged air filter restricting intake can affect combustion. Safety-wise, don't take it lightly; if the car doesn't move when you press the accelerator, pull over immediately and check the dashboard for any warning lights. Don't force it to avoid damaging the engine. For prevention, regular maintenance is key—clean the fuel system every six months to avoid sudden breakdowns on the road causing trouble.
