The steel lines that run from the injection pump to the injectors must be free of air bubbles. If there is air in the lines, the effected injector(s) wont see enough pressure to open, or will open at the wrong time. You'll have air in the lines if you've run out of fuel, or if you've removed the lines.
Luckily, bleeding the air out is easy. Just loosen the 17mm nut that holds the fuel line in place (one turn will do), and crank the engine until fuel dribbles out past the nut, then tighten the nut again. You'll want a rag handy to catch the fuel that comes out- it gets messy!
**CAUTION** in the picture below, the adjustable spanner that's holding the injector is touching the glow plug rail. Don't neglect to remove the spanner before cranking the engine, or the rail will short out through the spanner. (No prizes for guessing how I figured that one out...)
Make sure you keep the injector from turning while loosening or tightening the nut. You want to hold the injector on the part directly below the return rail (like the adjustable spanner in the picture). Don't panic if your injectors are slightly different to those pictured, just find the hex immediately below the return rail and hold them there. Oh, and this is the return rail:

Nothing says "poor workmanship" more than wrinkles in the duct tape.
