1985 Pontiac Fiero Coupe Grey RWD Manual GT

I bought this 1985 Fiero GT a year ago as a project car that didn’t run. I fixed the issue which turned out to be a faulty install on the aftermarket car alarm system. The engine starts but the manual transmission will not go into gear while the vehicle is running. This seems to be a common issue on the manual transmission equipped Fieros. The previous owner installed an aftermarket muffler, which is louder than stock. The interior has that 1980’s nostalgic vehicle smell.
