Answer 1

P0207 and P0208 these are fuel injector codes, the CKP sensor is the same for a V8 , the camshaft position sensor is in the distributor, The Cam and Crank sensor are the same for a V6 to a V8 the only thing different is the ECM. When you replace the ECM the VIN has to be flashed into the ECM this is what is preventing you from starting the vehicle
