No unless your OBD2 scan tool was built to also work with OBD1, and then if you got everything but the OBD1 adapter cable, you can not use an adapter cable to use your OBD2 scanner for OBD1. You can replace the last sentence to just a plain no for 99% of the time.
I make an GM OBD1 to USB cable. I sell it directly and on ebay. I am the only one selling it on ebay at this time. It works with and comes with the free version of TunerPro RT for Win XP -> 8.1. In my opinion TunerPro RT is by far the best program out there for scanning GM OBD1*, and the free version runs 100% after a 10 second nag screen. If you wish you can purchase a license for $39.99 and avoid the nag screen however that is never a requirement.
*93, 94/95 LT1s have a specific program written for scanning them that is nicer than TunerPro RT. It also btw is free to use and is included on the disk.
If you wish to scan using an android tablet or android phone that can work also. The same cable will work with the android scanner program. ALDLdroid is the only scanner program for GM OBD1 ALDL. It works using the TunerPro RT definitions so that means it will work with almost all GM OBD1 vehicles. ALDLdroid has specific requirements and they are listed on it's webpage. Also ALDLdroid is not free again see the webpage. ALSO -when using a USB cable with ALDLdroid you need to use the Android USB host mode function and host mode cable adapter. Check your version of Android to verify the host mode works on your device. The host mode adapter cable is cheap on ebay. (Host mode cable looks like a short USB android cable but it has a female end on it, hence the "host mode".
You can also use both TunerPro RT or ALDLdroid with bluetooth. I sell a GM ALDL OBD1 bluetooth adapter. The plus is that no cables are needed. You could leave it connected all the time, hid it under the dash/console and have it ready to connect whenever. The down side of the bluetooth is it is a bit harder to set up, so if your purpose is just to scan the USB version is most likely a better choice (and less expensive)

On ebay the cable is at http://www.ebay.com/itm/GM-...motive_Tools&vxp=mtr
The ebay version is the same but the price is a little higher to cover ebay fees.
The cable and software will work with all stock Fiero engines. and as far as I know for now, all GM OBD1 engines that I have seen swapped into a Fiero. (4.9, 3800 Series 1, 3100, 3400, quad 4. LT1)
