Ecm fuse blows when I hit ignition button

[Fatboyman]

2002 Fatboy cranks over but no start and I keep blowing ECM fuses. If anyone can help me, I thank you in advance....

Have you done any work on it lately? I would start out by checking for any shorts in the wiring. It's common for a short to cause a fuse to blow.
Do you have fuel and spark? it's a process of elimination so start with the basics.

Unplug the ECM and try a new fuse to eliminate a internal problem.

Welcome aboard from Gulf Coast AL. As Jeff mentions above have you done any work on it, and did the problem start after that. I did some work replacing my grips once and that happened, found I had a pinched wire on the stater button.

It happened about 2 miles after I degreased the bottom of the engine. I'm going nut trying to figure this out. Thank you for any help, I really appreciate it

 

[Fatboyman]

I wanted to add; it is getting spark, I can hear the fuel pump and no more blowing fuses

Sounds like you got it fixed, moisture maybe after degreased getting into ecm

 

[Jeff Klarich]

Have you checked for any codes? I assume it started and ran fine before you degreased it?

I would be disconnecting all the harness connectors to spray with contact cleaner and apply di-electric grease before any corrosion starts.
