I am beating my head in with this issue. EFI fuse blows randomly, I have found no patter. When it blow, it will keep blowing them and not start. I have to disconnect the battery first and then replace the fuse. Then it will run a good while till it blow the fuse again. Looking for a short but I can't find one but the battery thing makes me think it is something deeper. I am trying to track down the short right now but since it is operating normally it is fine. Guess I have to wait till it blows and get it home like that to figure it out. However the car works normal just does that randomly.
