You should do some forensics on the fuse. Did it break from age (typical failure mode) or did it blow. If it blew, you might want to test the glow plugs before sending another fuse down the drain.

Which brings up another point - don't just give the fuse a cursory look. Unscrew the fuse to see if it comes off in one piece or two pieces. These fuses can develop a hairline crack but look intact.
