I just did this on my 1999 rodeo so my answer might not be perfect for yours but I will try. The two cam gears on mine have a paint mark on them that lines up with two marks that are on each of the cam covers. The marks on the cam gears ended up pointing at about 10:30 o clock on the passenger side and 1:30 on the drivers side. Now at the same time that you have the cams lined up as I said, you need to have the crank pulley (dampner) lined up also. The mark for the crank was on the dampner itself as the dampner can only be bolted on one way. The mark that was on the block was at about 3 o clock.
Make sure not to move these gears indepentedntly too much so you dont bend any valves. you will not be able to use a light to do the timing when the internal timing is incorrect. Also, the computer in the car probably is setting the timing, co if you try to change in externally with a light the computer will most likely adjust itself back to where it wants to be.

It's more to it than aligning the marks since the cam pulleys turn about three times or more to one turn of the camshaft on this engine. You need to find someone that is experienced on this vehicle.

Small hole in the drive wheel's with treaded holes behind them. Turn the engine until the main shaft mark is at the top screw 2 screws through the holes and replace the belt

Yes be sure the number one piston is at TDC firing stroke or compresson stroke and line up the timing mark pointer is pointed at exactly zero. One more thing when aligning the camshaft sprocket or sprockets be sure that when you are rotating the sprocket for the cam it is rotating in the correct direction and also be sure you observe the intake valve for number one shutting as you bring the marks up to alignment points, the intake valve and the exhaust valve should be shut when the marks line up if not you could have the cam sprocket off 180 degrees, get it right the first time or you may damage a valve trying to start.

Timing belt installation
1. Ensure locking bolts located correctly  &  in the picture below:
CS = Crankshaft
CA = Camshaft
IP = Injection Pump
2. Ensure timing marks aligned .
3. Fit timing belt in clockwise direction, starting at crankshaft sprocket.
NOTE: "ISUZU" lettering on belt should be readable from front of engine.
4. Slacken tensioner pulley bolt . Push tensioner pulley against belt.
5. Ensure belt is taut between injection pump sprocket and tensioner pulley as well as crankshaft sprocket and camshaft sprocket.
6. Position tensioner lever  against tensioner pulley housing.
7. Remove locking bolts from sprockets  & .
8. Apply a load of 10 ... 12 kg to tensioner lever. Use spring balance .
9. Tighten tensioner pulley bolt to 80 Nm.
10. Turn crankshaft slowly 45 degrees anti-clockwise. Use spring balance to tension belt.
11. Repeat tensioning procedure at 45 degrees intervals for one anti-clockwise turn of the crankshaft.
NOTE: DO NOT turn crankshaft clockwise during tensioning procedure!
12. Fit tensioner lever to original position. Tighten nuts .
13. Install: Injection Pump flange , Camshaft sprocket flange , and water pump pulley.
14. Install components in reverse order of removal & refill coolant.
PLEASE DO RATE MY RESPONSE. THANKS!

Tips for a great answer:
Fig. 6: The number one cylinder is at TDC when the timing marks are aligned as shown (clikc image for zoom)
Fig. 7: It may be helpful to paint marks on the chain and sprockets if the marks are not easily visible
Remove the camshaft position sensor. Mark the position of the sensor before removal to help keep the ignition timing correct.
Fig. Line up the mating marks on the lower timing chain with the marks on the sprockets
Hope this helps.
