Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The code 22 in most cases is set due to a bad MAP (Manifold Absolute Pressure Sensor) . In order to determine if in fact it has failed you will need to do some testing. See the test steps in the link below.Copy and paste the links to your browser to open and view themhttps://dl.dropboxusercontent.com/u/104923897/MAP%20APr%2023.pdfThe lack of spark can be caused by any of the following,Defective Distributor PickupDefective Powertrain Control Module (PCM)Shorted WiringOpen Wiring HarnessSince you have replace the pick up and ignition module then you may have a failing PCM.
