Okay. That helps but I should have figured that as it makes more sense. Is this the fuse that you are referring too? See attached. If it is then that feeds to the ECM directly which means that the ECM is most likely the short causing the failure.
However, before you replace an ECM, how often does the fuse blow? If it is pretty easy to get it to do it, I thinking you should try something. This voltage feed is for the ignition control for the ECM. I am wondering if we have a coil back feeding through the circuit and the 15 amp fuse is blowing prior to the circuit board on the ECM.
If this happens easily can you unhook each coil one at a time and then see if the fuse blows? Clearly you are going to introduce a misfire but if the fuse doesn't blow like normal with one of the coils unhooked, you may have an issue with that coil.
Let me know. Thanks
