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 the ECM in a car to fail?

The most common source of ECM failure is in one of the wiring harnesses. If the wires to the transmission or fuel injectors become corroded, they can lose conductivity, leading to a failure. Fortunately, these issues can usually be resolved by replacing the corroded wires. If one of the wires shorts out to the frame, the ECM may fail entirely.

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 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.

What are the symptoms of a bad ECM power relay?

A bad relay may cause the vehicle to crank, but not start, or sometimes not even crank at all. 3. Battery drain or dead battery. A failed ECM power relay can also cause a battery drain or dead battery. If the relay shorts it can leave power on to the computer, even when the vehicle is turned off.
