I already checked that and its a regular red fuse(dont know for sure the amps) and it looks new, not melted or burnt. I mean could the fuel shut off valve get hot somehow? That thing is electronic controlled right? Cause after the engine stops it wont fire up for 5-7 mins, its like something got hot and it cools down..
