1. Fuel-related issues:
+ Low fuel and clogged fuel filter can starve the engine of adequate fuel, leading to stalling.
+ Faulty fuel injectors or fuel pressure regulator can cause irregular fuel delivery, leading to grinding noises and stalling.
2. Ignition system issues:
+ Worn-out spark plugs or damaged spark plug wires can disrupt ignition, causing inconsistent combustion and stalling.
+ Faulty ignition coil or distributor cap can also cause inadequate spark generation and stalling.
3. Starter issues:
+ A failing starter motor or its solenoid can cause grinding sounds while trying to engage the engine, leading to eventual stalling.
4. Transmission problems:
+ Worn-out transmission components, such as gears or bearings, can create grinding sounds and cause the transmission to lock up, leading to stalling.
5. Engine mechanical issues:
+ Worn-out engine components like bearings, pistons, or piston rings can cause knocking or grinding sounds and lead to engine failure and stalling.
6. Electrical problems:
+ Loose or corroded electrical connections can disrupt vital engine systems like fuel injection and ignition, leading to stalling.
+ A failing battery or alternator can also cause power loss and stalling.
