Timing belt how do i get a 1995 oldsmobile cutlass supreme in timing. like i need to know the timing marks

There is a red wire close to the battery in the front. It's not connected to anything. Apply positive voltage and that will run your pump for testing purposes.

On this website, you find fuse box diagram and description for Oldsmobile Cutlass Supreme (1995)

Oldsmobile Cutlass Supreme 1995 fuse box diagram Auto Genius

set the ff:
cranckshaft set the gear straight up = 12 o'clock (#1 piston must be at TDC)
camshaft set the gear straight down = 6 o'clock
to verify, the rotor of the distributor is pointing at #1 plug wire.

This engine it does't have a timing belt it has a timing chain.

locksmiths can come and make you a new key....from ignition barrel drum makes marks on test key or something and they file here an there till key works,,,,hope this helps.

It doesn't have any marks. Make your own before you remove the belt. If the belt was broke or you already removed the belt then you will have to remove the valve covers and install specialty tools into the ends of the camshafts to line everything up correctly.

Your cutlass has a timing chain, not a belt. A chain doesn't have regular replacement intervals.
