Does changing the water pump cause the timimg to be off? on 2001 Infiniti QX4

After changing my water pump on my truck my car started shifting very hard and slow while going from 0-20. I also changed my fan clutch and thermostat.

Asked by for the 2001 Infiniti QX4
considering the pump is driven off the timing chain , the odds are pretty good the timing is off. Did you do this job yourself , and did you have a service manual or 'just wing it'? One link off can give the symptoms you describe, sorry.
thank you so much, so what has to be done to fix it?
Who did the work and do they have (or access to) a service manual to see how to install the chain properly?
I will make sure that he looks at the service manual to install it properly, I don't have to purchase a new one do I?
any year manual that has the correct inf & diagrams , to install the chain &tensioner set-ups (that apply to an '01 QX4) should be okay.Otherwise , if you have a friendly neighborhood nissan or infiniti dealer around , they might be able to help some.Years ago when I had my own shop , before everyone was on-line I would routinely go in and borrow dealer manuals for job specs & special procedures (I also purchased a lot of parts from them). good luck.
Thank u for all ur help.
No you don't need to buy a new chain or pump just set it up correctly ---- sorry about my goof!! Mis-understood your question about needing to buy "a new one" never mind , I thought you were meaning the service manual (big DUH moment!!).Hope you see this soon enough.
