Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.If you are sure you have proper fuel pressure then check and see if you are getting injector pulse. You can check it with a standard 12 volt test light by placing the test end on the power side of any one of the injector and the ground end on the other side and then crank the engine over. If you have pulse the light should flash. If the pulse checks okay then check and see if you have good spark to the spark plugs . Post back with the results and we can work from there on this.
