how is the injector connected? like normal but spraying into a cup instead of the cylinder? ifso id expect a good injector to spray fuel, all be it a verry fine mist. and yess when the pumps break down, they still produce normal pressure, its the injectors that clog that cause it not to start, and the pump causing the injectors to clog
if you can do the work your self, its 100 for a second hand pump, and around £90 per injector (recon)
