You are quite right, there are no timing marks on the camshaft pulleys. One of the marks on the crankshaft pulley, the one that is furthest counter-clockwise, lines up with a raised mark on the oil pan,at about 5 O-Clock as viewed from the front. The special tool to position the camshafts is a straight bar that aligns the slots on the rear of the camshafts. These are supposed to be aligned before the belt is removed. If the engine is turned without the belt installed, some of the valves can be damaged. Hope this helps.

Try this diagram, it may help.

To set the timing you should turn the No.1 piston to TDC, then turn the cam to where both valves on No.1 are close. The timing mark on the sproket should now be in line with the mark on the cilinder head. With No. 1 still on TDC fit the chain.
After fitting turn the engin a few times by hand to make sure there's not a valve pushing against a piston.

are you sure that the tensioner is still good I have the same engine in my 94 ranger and have had to replace the tensioner 2 times

The timing chain diagram & procedures for 2000 Toyota Corrola 1.8 engine:

Special tools:
1. Crankshaft pulley holder - Tool No. 09213-70010/11.
2. Crankshaft pulley puller - Tool No. 09950-50012.

General precautions:
1. Disconnect battery earth lead.
2. Remove spark plugs to ease turning engine.
3. Turn engine in normal direction of rotation.
4. Observe tightening torques in pictures below.
5. Do NOT turn crankshaft via camshaft or other sprockets.
6. Do NOT turn crankshaft or camshaft with timing chain removed.
7. Mark position of crankshaft position (CKP) sensor before removal.

Valve timing procedures:



1. Ensure crankshaft pulley and timing chain cover TDC marks aligned [1].
2. Ensure teeth timing mark on each camshaft sprocket aligned.
3. 1ZZ-FE/3ZZ-FE/4ZZ-FE [2].
4. 2ZZ-GE [12] OR [13].
5. If not, turn crankshaft pulley 360 degrees.
6. Remove chain tensioner, tensioner rail and chain guide.
7. Check chain for wear.
