Up until 2002 the fuel pressure regulator was vac controlled and mounted in the fuel rail on the intake manifold.
After 2002 I think it is part of the fuel pressure sensor which still mounts on the rail.
You may have to check with the dealer to see which version your engine has.

Stop cussing. Fords hate foul language and will beep you out for dropping the F word like a PG13 movie.

If you're finding it difficult to service/repair your
car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus i know a website that has very good manuals online, without expiry i.e. for lifetime. www.reliable-store.com

That code is for 02 heater circuit. Replacing the sensor may not fix it. I'd have to check voltage and ground for the heater circuit wiring. The voltage is fuse protected, red wire.

Might be but it is difficult to speculate about what happened 20,000 miles ago.

Dirt in all its forms shorten the life of an auto transmission, unfortunately the transmission produces much dirt for itself so it will eventually self-destruct. Boy-racer starts, towing, long slow hills, heavy slow-moving traffic and suchlike are all things that cause the tranny to create more dirt and hasten the end. When a tranny gives mechanical trouble best practice is a complete strip-down and a thorough clean every time especially when a close examination of the oil pan reveals metal swarf - the big problem is the extended downtime and a great deal more expensive than most owners would tolerate and so repairs are carried out instead, hopefully striking the correct compromise between the cost and the life expectancy.

I suspect the auto tranny technology hasn't kept pace with engine technology as in my experience they are failing earlier and in greater quantity than ever before and in my limited experience 82,000 miles isn't so bad...

A broken shaft and damaged converter splines would certainly produce metal swarf and best practice would be to completely dismantle the transmission for a thorough clean but as the work was under warranty it is unlikely that happened.

that item is called a relay switch. it toggles on and off depending on which electrical component it is connecting. if it's blown, they are cheap and easy to replace like a fuse, but you'll need to look at the fuse box chart (usually on the underside of the lid) to determine which one and where it's located. You can't look inside the relay to determine if blown, but you can replace them one at a time to test...
Also, if you're experienced in electrical, a paper clip can be used when the relay is out, to connect the circuit that you need. use tools and or gloves when attempting this method.

If this all happened after pan gasket change, chances are you knocked the oil pump pickup and the pump is sucking air. You've lost oil pressure. Fix that. Do NOT add washers. That's not your problem.

Who told you the alternator was fine? Sounds exactly like an alternator issue, fuel relay cant stop your dash gauges from working. An alternator should be putting out 13-14.5 wolts with the car running. Do you have any lights on the dash? like a battery light or anything out of the ordinary?

What I think Bank 1 usually refers to the O2 sensor before catalytic converter. I have been told in the past many thing can set it off. I have gotten them before for O2 sensor and took my negative battery cable off the batter and it cleared the code. Sometimes it comes back sometimes not. I did find some info.

One thing I need to add if you pull the cable off the battery and your radio has a antitheft program in it you will have to provide a code to get your radio working again.
