Its also worth checking your Crank Position Sensor. Its No.13 in Cathy's diagram, right underneath the alternator. If its this at fault then (when you do a proper diagnostic run) it will show up as code 11.
If this is not connected properly then you will get fuel and air, the engine will turn over and over but give you no spark. This is the one which should be disconnected when dry cranking after oil change.
