Either you are not getting a hot enough spark, the fuel pressure is too weak, the timing is off, or the engine has low compression. Check all those items and let me know what you find. NOTE: THe spark should be a good hot blue snapping spark. Also, make sure the injectors are getting power. See if it will start with starting fluid for a few seconds. If it does, then it sounds fuel related.
