4. Investigate Carburetor Or Fuel Injector Issues
When dealing with a vehicle that won’t stop when the engine is running, it’s crucial to thoroughly investigate the carburetor and fuel injector for potential issues. Both components are vital to the engine’s function, and any problems with them can cause the engine to keep running when it should be stopped.

A dirty or clogged carburetor can cause the engine to keep running even when the vehicle is turned off. Cleaning the carburetor is a simple process that can often resolve this issue. By removing any built-up dirt, grime, or debris, you can restore the carburetor to optimal functioning and prevent the engine from continuing to run after it’s been turned off.
4.2 Repair Or Replace Fuel Injectors
If cleaning the carburetor doesn’t resolve the problem, it’s important to inspect the fuel injectors. Over time, fuel injectors can become worn or faulty, leading to fuel leakage or improper fuel delivery. Repairing or replacing the fuel injectors may be necessary to address this issue and ensure that the engine stops when the vehicle is turned off.
