I need the titening torque specs on a Isuzu 4hk1, big end bolts,cilinder bolts and injector timing marks on the flywheel and cam gears

Look here

https://barringtondieselclub.co.za/isuzu/4h.html

Toyota Yaris Main and Big end Torque settings:
Tighten the main and big end bolts in sequential order and in two steps.
Main bearings. Stage 1.
22 ft lbs.
Stage 2.
44 ft lbs

Big end bearings.
Stage 1.
11 ft lbs.
Then Rotate bolt head a further by 90 degrees

Head bolt torque must be done in 3 steps:
1st 22 ft lbs
2nd 43 ft lbs
final 47 ft lbs
use this sequence of tightening:
9 - 3 -1 -6 -8
7 - 5 - 2 -4 - 10

Flywheel spec:
65 ft lbs

Could it be a F-150 instead?

These specs are for stock-type bolts with light engine oil applied to the threads and the underside of the bolt head. Moly and other lubes offer reduced friction and increased bolt tension, which will affect the torque figure. If you use after-market performance bolts like ARP's, you should follow the recommended torque specifications.

Remove timing belt cover and the timing belt. Line up the cam gear timing mark with the mark that is behind it. Then, set the crankshaft pulley timing mark to zero degrees or whatever the book says. Then re-install the timing belt and re-torque the timing belt tensioner to the proper torque. Turn the engine one full turn, with a breaker bar and socket. Re-check the timing marks on the crankshaft and camshaft. Re-install the timing belt cover and everything else you took off to get to the belt. Be sure to torque the crankshaft pulley bolt to specs.

I googled for you and 3rd hit , is
http://www.nationaltruckspares.com.au/P_Isuzu-Isuzu-4HK1-NPR75-Etc-Torque-Specification-.aspx?id=3650

see the spec there. in nM>?

it states
M14 bolts 98 nm then 147 nm then + between 30 to 60 Degrees
M10 bolts 38 nm

timing marks

Main bearings - stage 1-80 Nm; stage 2-100Nm.Big ends-stage 1-22Nm,stage 2 -45Nm.Flywheel/drive plate-55Nm.Crankshaft puley-120Nm.Cil.head as main bearings.Valve clearance - cold - inlet-0.15 , exhaust - 0.25. Timing 6/800 at sea level.Good luck!

normally 110 nueton metres. use nut lock and once you have torqued you will feel if you have to tighten it a bit more.
