... on mine, there is a fuse that powers the left bank and a fuse that powers the right bank. If one or both of these fuses blows, the engine will either run very badly or not all ...
OK, this is one of those "you're both right" moments...
On the DDEC two-strokes, the injectors are mechanically operated by pushrods, in much the same way fully mechanical injectors are operated (as opposed to, say, a high-pressure common-rail system found on more modern engines). However, there is also a small solenoid in each injector that is opened and closed electrically on command from the ECM, which controls the fine injection timing and amount of fuel delivered to each cylinder.
If the ECM does not call for fuel, the solenoid does not open, and the injection plunger instead pushes all the fuel through the bypass pathway and back to the return. No fuel goes to the cylinder. This is, in fact, one of the ways to test your injectors -- the DDR or Pro-Link will let you set any particular injector to zero-fuel to see if there is any effect on the engine.
If the injector bank fuse blows, no fuel will be delivered to that bank, even though the engine is turning and the injector pushrods are operating.
