If it is blowing when you start the car, the problem is still with the starter. If it is blowing while the car is running, you will need to get a wiring diagram (try Alldatadiy.com) and check each device wired to that fuse.
Testing needs to be done to know for sure , we would only be guessing if we mentioned any part or system as being the problem . Rather then guessing take the vehicle to a qualified repair shop an have diagnostic's done . Viewing scan data on a professional type scan tool , looking at fuel and ignition systems data parameters . Where are the fuel trims at,short an long term ? +or - 5% are the O2 sensors switching normally ? What's the MFS sensor showing ?
