04 Suzuki Verona ECM fuse problems
Hi all!
My ecm fuse ( fuse 15) in the underhood fusebox blows when the engine is cranked. There is a short to ground somewhere in this circuit. Fuel pump relay and fuel pump have been replaced with no change.

Any experience with this out there? Any thoughts one how to trouble shoot?

Any help would be greatly appreciated!
Thanks!!!
M

RE: 04 Suzuki Verona ECM fuse problems
I would do the usual diagnosis stuff. Pull the relay and see if the fues hangs in there. At that point you know where you are going. With the relay out, if the fuse still blows you should head toward the crank circuit. You may want to invest in a test light and a circuit breaker to rig something suitable for your testing.

BTW, it may not be a direct short. It may be just a high draw so you will need to watch for other symptoms. (I have found aftermarket pumps to be problematic)
Figire out what else is in the various circuits and start disconnecting things. Follow harnesses and look for physical damage or any place where body work was done previously. Those are always good hints.

Let us know what you find as it may help someone else.
