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 good spark then lets check and see if you have proper fuel pressure while cranking, normal pressure should be right at 55 to 60 PSI . If the fuel pressure checks okay then the next steps would be to check for injector pulse. If you can check these and post back with the results we can work from there. While you checking these it would also be useful if you could scan the computer system and see if there are any fault codes setting and post back with those as well.
