You can't. You need to replace the faulty and worn parts.
Most (not all) Fiero engines require the engine be removed from the car and the seal removed after that. The engines use a one piece seal in most engines. It is also possible to remove the transmission to do this, but either way you need to separate the engine and trans, pry out the old seal, and install new.
Yes, the injection system will not provide the correct mixture if the engine temp does not get to 150 degrees F
the fuel pumps on fiero's are in the fuel tank and I have never seen a shut off switch on them just a fuse in the fuse box under the dash

Your IAC valve next to the throttle body is likely stuck open. Remove it with a 1"1/4" socket, clean it and let it sit overnight, and then reinstall it. If it continues to stick open, it is defective and you will need to purchase a new one. The IAC, when it is stuck in the open position, causes the 2.8L Fiero V6 to feel like it has a sluggish idle. You should also be seeing problems periodically when you start it, such as the idle jumping up when it first runs, and then dropping below 1k RPMS.

Engine comes out through the bottom, need to pull the cradle with it. If engine re & re is new to you I suggest you get a manual as it's too lengthy a procedure to type it out. A good bit of automotive knowledge is definitely an asset to be successful
You need to replace the valve, which will require removing the head. While there, make sure that the valve seats are undamaged, and since it is apart, you are better off replacing all the valves, as well as the valve stem seals. Check the price of valves, as they can get expensive, but most of your cost will be labor.
