Loosen the No. 1 injector and crank the engine. If you see fuel being expelled, your fuel pump is working. If not, let it crank a few times to be sure the air gets forced out. If the engine tries to start, tighten the injector (while it is cranking - and spraying some diesel) and it probably will start. When you crank the engine for a while, it is often a good idea to close the raw water intake. This may seem counterintuitive, but the engine will certainly not overheat during cranking (or for quite a few minutes after it starts). The closed raw water intake will keep the engine from filling the exhaust elbow then flooding the engine with seawater. Do reach in and open the seawater inlet once it restarts - mind the "spinning" parts on the front of the engine.
