Why does my ECM keep blowing the fuse?
Hi there. If the ECM fuse keeps blowing, then there is a definite electrical short. Most of the time the short is in the ECM, but it may have a short in the wiring going to it. I usually isolate it by going through the wiring schematic and disconnecting areas of the circuit until I find the short.
What causes a fuel pump fuse to blow?
When the fuel pump begins to fail it overheats, causing it to drain more amperage (amp); if the amps exceed the amount of amps the ECM 1 fuse allows, the fuse will blow. Replacing the fuel pump should correct this problem. The ECM 1 operates via voltage sent from the battery.
Why does my ECM 1 make a clicking noise?
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.

Can a bad ECM cause a car to not start?
Of course, there are other reasons a car may not start, including a bad starter or a blown alternator. If you’ve replaced these parts and your car won’t start, your ECM is the most likely cause. Once again, you’ll need to take your car to a mechanic to be sure.

What happens when an ECM power relay goes dead?
If the relay shorts it can leave power on to the computer, even when the vehicle is turned off. This will place a parasitic drain on the battery, which will eventually cause it to go dead. The ECM power relay is one of the most important relays as it provides power for the vehicle’s computer system.
Why does my ECM 1 fuse keep blowing?
If the wires leading to the O2 sensor rub against the exhaust, it creates a ground; once the O2 sensor is grounded, the fuse to the ECM 1 blows. The O2 sensor must be installed in a different place to ensure the wires do not short-circuit.
