After some unfortunate events my Nissan Primera 2.2 DI (2002 yr.) bent one valve (while tying to start a car) and broke a camshaft. I took off the cylinder head and took it to the shop to do full repairs (regrinding, changing valve, washing etc.). Today I was preparing to assemble everything back together and while reading workshop manual, I noticed, that my fuel pump sprocket punched mark is not aligned with marked primary chain link. I think this sprocket could have skipped some links. So I definitely can time the crankshaft with camshafts, but i’m not so sure if fuel pump needs to be in exact alignment with crankshaft? As i understand in common rail engines, injection is timed via injectors and ECU, thus fuel pump is just constantly holding required pressure? I know I could align sprockets by stripping primary chain, but it’s just so much of additional work. I’m adding a primary and secondary chain alignment scheme, maybe it will be clearer.
I really don’t want to assemble everything only to have injection, fuel pressure faults, so please, can anyone give me some insight?
Thank you, and sorry for my english, I’m not a native speaker
