Also horn dosen't work, not a fues issue.
When the key is put on to run, the fuel pump will prime for 1-2 second 2 times each. Once the engine is running, it will run constantly. It's a return style system, so it's constantly circulating fuel.
As far as the issue, will need to know what symptoms you're having.
The horn can be hit and miss, you might start with hooking up a test light to the wire that's hot and see if it's getting any power. If not, work back, it's possible that the switch isn't functioning anymore.
