I dont know of any inline fuse,could be.I do know there has been problems with the fuses themselves.If you havnt done so pull each fuse and put it back in,I have heard of some people that have had to do that because of the cheap fuses and bad connections..Was it running when you bought it or did the bank tell you the ecu was to cause of it not starting? There are many more members here that will give you more and Im sure better advise then me so dont give up.
