Do I need to replace EMC again.

Question

Replace ECM few weeks ago. Then installed TS  6 way chip. Truck will not start and I get P0603 and P1662 code from cumputer.

Answer 1

P0603 Continuous memory failure (KAPWR)

P1662 Injector driver module

No you should not have to, something got missed, Even with a P0603 the engine starts and drives, P1662 this will stop you from starting , and it can also be set do to cranking and no start condition, A faulty Camshaft position sensor will set this code, but for some reason will not set a cam sensor code, A faulty IDM relay this will cause the code to set, or no power to the IDM circuit and a no start, The TS 6 way , never seen this a cause for a problem
