The ECM one fuse keeps blowing?

Hi,

That fuse powers all fuel injectors, the vehicle control module, the ignition coil, and the crankshaft position sensor.

Because we can't disconnect any of them to see if the fuse doesn't fail, start by inspecting the wiring to each component. It will be a pink wire. Check at each fuel injector to see if the wiring or a connector is damaged and the same with the VCM and crankshaft position sensor.

I attached the wiring schematic below and highlighted the wiring related to the ECM 1 fuse, so you have a reference.

Let me know what you find or if you have other questions.

Take care,

Joe

See pic below. Note: I'm assuming this is a 5.7L V8 engine and not the diesel. If that is incorrect, let me know.
