Answer 1

P0202 P0203 P0205 P0208 And P1262

P01262 The ECM detects a circuit fault related to the high voltage to cyinder 2,3,5,8

 

When there is a circuit problem with the injector on that circuit voltage the FICM (fuel injection control moduel) will disable the all the fuel injector of that affected circuit voltage.As long as P1262 is not set by itself this will not be the FICM being at fault , just a injector or it connection,  this is a incorrect current on a fuel injector. or the fuel injector The tool for this fix is the use of a Volt/ OHM meter . Use Caution when working with and at the fuel injector this is High voltage
