How do I find the timing mark for a 1992 Izusu Trooper?

The timing marks are located on the lower section of the timing belt cover above the crankshaft pulley. The mark is on the crankshaft pulley. The timing cannot be adjusted on the 3.2L engines. The timing is computer controlled by the ecm wich receives a signal from the crankshaft position sensor. The timing marks for the timing belt are on the camshaft pulleys ( aligned with dots on the front of the metal rear piece of the timing chain cover) and the lip behind the crankshaft timing belt pulley. It is a half circle slot that you align with a horizontal line on the oil pump at about 3 oclock ( right hand side ).
