To be clear, does the engine turn over but does not start? If so have you checked for spark?


What kind of OBD2 are you using, if you have a misfire on cyl#3 it should be throwing a random misfire code too....id check for spark on all cyl. and then check your fuel pressure, if those come up good, start checking sensors.
