Why Won't My Automatic Transmission Car Start?

Reasons why an automatic transmission car won't start: 1. Check the car battery, as it might be dead; 2. There could be an issue with the spark plugs; 3. Verify if the car is out of fuel, and also check if the gear is not properly set. Unlike manual transmission vehicles, automatic cars won't start if the gear is in R (Reverse) or D (Drive) instead of P (Park) or N (Neutral). If the throttle body is dirty, cold starts may fail because carbon deposits block sufficient air intake needed to start the engine. Pressing the accelerator slightly can increase the throttle opening and allow the engine to start. It's also recommended to clean the throttle body. Another possible cause is the absence of antifreeze. Some car owners use water or low-quality antifreeze, which can freeze in extremely cold winter conditions, blocking the entire cooling system and even cracking the engine. This prevents the water pump from functioning, making the car unable to start and potentially damaging other engine components.

I've encountered automatic transmission cars failing to start multiple times, and after summarizing, there are quite a few reasons. The most likely one is a dead battery, such as forgetting to turn off the headlights leading to depletion; next is a starter failure, like a seized motor or a damaged relay; not being in the P or N position is a unique mistake for automatic transmissions; there's also the fuel pump malfunctioning or the ignition system having issues. I remember once at a gas station, it wouldn't start because the anti-theft system mistakenly locked—triggered when the key battery was almost dead. This is about safety; if it happens, don't stubbornly try multiple times; attempt a push start or get a jump start, then go to a professional shop for inspection as soon as possible. In non-emergency situations, test the battery voltage yourself first; simple prevention can save a lot of trouble.

What does a bulb with an exclamation mark mean on a car?

Yellow bulb with an exclamation mark: This is the lighting fault indicator, indicating that there is a fault with one of the car lights. Solution: Visit a 4S shop for inspection and repair as soon as possible. Alternatively, you can check it yourself, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. The exclamation mark is a common fault indicator in cars. Besides the yellow bulb with an exclamation mark, there are four other forms of exclamation mark indicators: an exclamation mark inside a triangle, an exclamation mark inside a yellow gear, an exclamation mark inside a circled parenthesis, and an exclamation mark inside a parenthesis with a horizontal line below. Here’s a detailed analysis: General Fault: An exclamation mark inside a triangle. If this symbol lights up, it indicates a fault with the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: An exclamation mark inside a yellow gear. This is the automatic transmission fault warning light, indicating a fault with the transmission or that the transmission lubricant is below the normal range. Transmission oil should be replaced promptly. Brake System Fault: An exclamation mark inside a circled parenthesis. This represents a brake system warning, indicating either a brake system malfunction or low brake fluid level. Immediate inspection and repair of the brake system are required to avoid accidents. Tire Pressure Anomaly: An exclamation mark inside a parenthesis with a horizontal line below. This represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range.

What is the RPM at 80 mph for a car?

At 80 mph, the RPM of a car ranges from 2000 to 2500. The reasons for high RPM are: 1. Sudden increase in throttle opening; 2. Fuel injector leakage or blockage; 3. Slippage or damage to the air conditioning clutch; 4. Air intake system leakage; 5. Insufficient engine power output. Solutions for high RPM include: 1. Adjusting the throttle opening; 2. Replacing the fuel injector, air conditioning clutch, air intake system, or engine. The reasons for unstable RPM gauge readings are: 1. Oil accumulation and carbon buildup in the throttle; 2. Dirty intake tract; 3. Blockage in the fuel system, particularly the fuel injector; 4. Faulty intake pipe.
