Starts Then Dies Immediately

A burning smell from your vehicle has several distinct types. Burning rubber can mean a slipping belt, dragging brakes, or a hose touching the exhaust. Hot oil smell means oil is dripping onto a hot surface. Burning plastic or electrical smell means wiring or insulation is overheating. A sweet or caramel smell usually points to coolant. Identifying the smell type and when it occurs helps narrow the problem before any parts are checked.

Your car won't start, meaning the engine doesn't turn over when you turn the key or press the ignition button. This is usually caused by a dead or weak battery, a faulty starter motor, or a bad alternator. Check your battery connections first, and if that doesn't help, you'll likely need professional diagnosis to identify whether it's an electrical issue or a fuel/ignition problem.

A steady check engine light means the vehicle computer stored a fault related to the engine, emissions, fuel, ignition, air intake, or sometimes transmission controls. The only accurate first step is reading the code, then diagnosing the system the code points to.

Engine noises at idle, startup, or under load need to be separated by location, oil pressure, RPM change, and whether the noise is ticking, knocking, rattling, or hissing.

Engine fails to crank or turn over when you turn the key.
