You need to first check all the fuses, the connections at the battery cables, and the connection at the cable to the fuse box. My guess is that there is likely a loose connection at the fuse box or at the main battery cable to the starter, and pushing on the fuse box moves everything in just the right way to make a better connection. It’s also very possible that there was another fuse blown when the other work was being done. If the connections are good, and the fuses are all good, then you should have a professional technician, such as one from YourMechanic, diagnose the no start issue that you’re having.
