okay guys so I'm having an issue ever since i changed my roll pin when it broke i been having random starting issues, it will crank but no start. then another time when i changed my fuel pump same thing i ended up jiggling the fuse box a lil bit and then it turned over. now today same thing this time it ended up being my fuel pump fuse (15) . i changed it got it to my house and tried to start it again and i blew another one.
I'm sure i have a short is there somewhere specific i should look for ? or should i just remove fusebox and try finding the issue.
