If it is a 95, you can be sure he did not scan it correctly, especially if using an OBD-II scanner.
Service engine light not throwing any codes?
So last night, after struggling with a mysterious loss of coolant for a while now, I finally caught a drop coming from my water pump. A couple of days ago my service engine light came on for a few minutes and went back off, tried taking the car to O'Reillys and the guy said no codes to be found. Driving home the light comes on again, next time I start the car it's gone. I plan on having the computer scanned again because I'm not sure the guy did it right, hood sticker says its obd1 but guy said its obd2 connector.
From what I've read you need to manually enter vehicle info in this case but the guy wouldn't listen to me and got error, yet still managed to show me a "no DTC codes found" or something like that. So aside from checking again, does anyone know of a cause for the SES light that wouldn't throw a code? Could it in someway involve my leaky water pump?
Edit: current car is 95Z M6 bone stock.

There's a good obd1 scan program available in the 4th gen section. It's specifically made for 94 & 95 f-bodies. All you need is a cable to hook car's dlc to usb port of laptop or notebook. Get cable at ALDL OBD1 OBD cable OBDI OBD2 engine codes get the 16 pin model.
Appreciate the responses. Considering this is my 4th Lt1 with 3 of them being 94-95 that cable would certainly be a good thing to have around.
If you want to scan the 94 lt1 cars, you will need a 2nd cable with the 12 pin dlc end, or make an adapter that goes from 16 pin 95 dlc connector to 12 pin of 94.
That's what I did with my 16 pin obd1 cable for my 95. I also use the cable to scan my 90 camaro, which uses the 12 pin GM type dlc. Made an adapter that converted 16 pin to 12 pin dlc end.
