Hard Starting, poor Idling knocking sound after waterpump change

Toyota 2C Normally Aspirated Engine:

Mga Sir,

Pinalitan ng mechaniko ung water pump pero kailangan tanggalin ang timing belt.

Pag kabit nag hard starting tapos maingay di ko alam kung fuel o mechanical knock eh.

Pero di naman ginalaw ung posisyon ng crank and camshaft eh.

Ano kaya magadang gawin? Nasira kaya ang camshaft or valves ko?

Thanks in advance.

Better to have it double-checked to be sure. Even if you don't think you moved anything, you're not sure unless you've checked the alignment of the timing marks.

I just fired him.

Sabi nya injector daw. Ung tunog kasi parang pina amoy mo un diesel ng lighter fluid nag aaccellerate ung tunog na parang sasabog ung makina. Chinek ng kapatid ko ung timing may konting off siguro 1 teeth ng belt tapos ung injection pump imbis nasa uno ung pointer nasa kabilang dulo. Ang pinagtataka ko bakit wala sya gaano usok at tumatakon naman. Di ko pa alam kung ano nagnyari kasi iniwan ko kapatid kong engineer na gumagawa baka bukas may update na.

Halos ganito ung tunog pero walang ganyang tunog dati. YouTube - ‪6.2 diesel injector knock‬&rlm;.
