There are three marks to line up... before you remove the lower timing belt cover there are the marks on the little gauge that is integrated into the cover that line up with a mark on the main crankshaft pulley (to actually time it while the engine is running) there are also marks on the camshaft sprocket (big sprocket at the top of the engine seen with the upper timing cover removed), that lines up with a white mark on the upper rear plastic timing cover. And finally if you replace the timing belt there is a mark on the crankshaft sprocket that lines up with a mark cast in the face of the aluminum engine block. mnemonic76 1988 Pickup owner
You can set the injector pump timing on a 4HF1 Isuzu engine by adjusting the fuel injection screw. The adjusting screw will restrict the amount of fuel to be injected.

The timing marks on your Isuzu 4hf1 engine can be set by looking at the timing marks on the timing belt pulley. The timing belt marks are facing towards the front of the automobile.
