Fiero "Pre-Flight" Electrical checklist

by Oliver Scholz


Whether you're buying a "new" Fiero or going on an extended trip, whether you're a Fiero expert or a novice, you're never sure your Fiero is completely operational and all its circuits are functioning perfectly. This is why I have compiled this checklist. It allows you to check virtually all functions of a Fiero and quickly determine if something is broken or not working right. It does not cover all cases or all electrical problems, but it should catch the majority of them. If you think I left something out, please feel free to contact me and I'll add it to the list. This checklist does not require any tools, just a pair of eyes (actually, one will do too), and your hands. A helper can speed up the process, but you can also do everything by yourself.

This list checks all bulbs, switches and many other components. It can not check everything, but pinpoints a lot of problems that might go unnoticed until after you have bought the car.

The list

That's about it! If the "check engine" light works, the ECM should check all sensors, and the test drive should have revealed problems by setting a light. If you want to be sure, bring a Torx screwdriver and remove the cigarette lighter plate and check for trouble codes by shorting the A & B terminals on the ALDL connector.

One other problem area that this list can not check is the fuel gauge or its accuracy. There is no quick way to check it unless you know the state of the fuel tank.

If there is anything else that can easily be checked, please drop me a line and I'll add it to this list.
