If you do in fact have fuel pressure and spark, the injectors must not be opening. If you have a volt meter or test light, see if the ECU is sending 12 volts to the injectors by pulling one injector plug and connecting the meter or light up to it and crank it over. The best method for testing an ECU is finding one to borrow that is known to be good and substituting it. Of course the trick is finding one to borrow. jp
