Can a Car Function with a Blown Main Engine Relay Fuse?
The answer to this question is no. A car cannot function with a blown main engine relay fuse because the fuse supplies power to the engine control module (ECM), which in turn controls the engine’s ignition, fuel injection, and other vital functions. Without a functioning main engine relay fuse, the car will not be able to start or run.
Conclusion
The main engine relay fuse is a critical component in a car’s electrical system. If the fuse blows, the car will not be able to start or run. If you suspect that the main engine relay fuse has blown, you should inspect the fuse and replace it if necessary.
