Well since you have a TPI the code 36 will = Mass Air Flow (MAF) Burn-Off Circuit. The code 12 is a normal code that you should always get when you check for codes. It simply means that the engine isn't running and the ECM isn't getting a reference pulse from the distributor because the distributor isn't turning.
