A misfire will cause the MIL to come on, and then several key cycles/drive cycles without the misfire will turn the MIL off. The injector harness is partially encased in a plastic shroud. If you don't see any exposed/frayed/broken wiring there then a small flathead screwdriver will open it up so you can inspect inside. Carefully follow the wires from each injector as far as you can (don't pull out ALL the wires, keep it neat so it's easy to put back together) and check for exposed wires or melted wiring insulation or anything you think would cause a short.
It may not be a shorted wire. Locating shorts can sometimes be tricky but other times they'll jump right out at you. A careful inspection is always where you start.
Cleaning out the valves like SlackJaw mentioned is another simple thing and should be done regularly on lightly driven vehicles. Your symptoms sound like a bad/shorted injector though. Have you used any fuel system/injector cleaner recently?
EDIT: a shorted injector will flood the cylinder. Pull out #1 plug again and smell it. If it smells strongly of gasoline then I'd be looking at finding the short.
