Welcome to GMTC. The crank fuse protects the circuit from the starter to the ECM. The power comes from the starter so the ECM is probably OK. You need to check the wire from the CRNK fuse back to the starter and then once you have power back to the fuse box check the wire from the CRNK fuse to the ECM. If the ECM were bad the truck wouldn't run.
