Do you have spark? And do you have fuel?

You must check for spark on all cylinders, use a spark tester, spark should be bright and blue and defined. Not orange and weak looking.

After that you have to check the fuel pressure, how much do you have at the fuel rail. Use a check guage dont just push the schrader valve down and assume you have enough if fuel sprays out.

Let me know what you come up with.
