1998 Chevy Cheyenne ECM bad?

98 chevy C2500
The truck would not start. The starter turned but I realized I had no fuel pressure. I replaced the fuel pump relay and fuel pump with no result. With the fuel pump hot wired it produced the 60 psi required at the fuel raill but the truck still would not start. I hooked my scanner up to the vehicle and it reads "link error". I cut the truck off for 10 seconds and still the same "link error". I noticed that the ECM 1 fuse has blown and blows every time a new one is installed.
