Injector register fault showing after replacing timing chain

I've got a 2010 d40 yd25 Navara. I bought it cheaply as it had a CPS fault showing. I changed the CPS. IFor the camshaft to be out it would be a timing chain issue as this seems common. I replaced the timing chains following all th instructions carefully. When I started it, it was still in limp mode and a scan showed P1622, injector registration. As I hadn't touched the injectors I figured I must have got the fuel pump out of time. I started to strip it down again, the fuel pump locking pin slid straight in with the crankshaft at TDC. The marks in the cam sprockets were perfectly on the mark. When I put the locking pin in the balance sprocket it goes about a third of the way around (4 o'clock) with the crank at TDC. All the literature only mentions the balance sprocket locking hole near TDC.
I'm at a loss as what to do next.

Have you tried to do a ECU reset to see if this fixes the problem?
