Hello and welcome to JustAnswer!

If the engine cranks but doesn't start you're most likely missing fuel or spark, but it could also be a cam timing issue, an exhaust restriction, or possibly contaminated fuel

Most issues that will cause a loss of spark will set a fault code so if no related codes are setting then odds are you do have spark.

The next step will be testing spark and fuel pressure. Has this been done?
