What happens if ECM fuse is blown?
If an electrical wire gets burned or damaged, the cables pointing to the ECM is going to short-circuit. Once that happens, a power surge can result, and if it the exceeds the fuse’s limitations, the fuse is going to blow. Once you have checked all those spots, check the wires and the coil on the back of the engine.
How do I know if my ECM fuse is blown?
The voltage or amps surge, causing the ECM 1’s fuse to blow. When the starter fails you will hear a clicking noise or the engine will be hard to start.
What does the ECM fuse control?

Can a blown fuse cause electrical problems?
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. …
Where is the ECM fuse located?
