Sounds like fuel pump is out and know there's not a reset best I can remember

The ECU wasn't bad. The power steering unit is. The ECU compensated for the bad unit, until it wouldn't take it anymore. Replace the steering unit under the dash. Just a note though. I would do a wiring diagnostic first, to make sure all the wires are good.

Motor relay circuit malfunction, check power steering ECU!

Recommend replace CKP (crank shaft position) sensor 1st, clear codes and recheck.

There is 2 system in O2 sensor one is the sensor itself
and the other one is the heater
the code you have means the heater is not working look for the fuse or find out why heater is not working
don't put any anti seize lubricant on O2 sensor no ground for heater
hope it help

Sounds like a crank sensor to me. I believe this will be found just below your bottom pulley [ crank pulley] . This is responsible for getting power to the coil. These are sometimes hard to get out . I just broke it off and used a socket. I don\'t know how you can test this sensor unless you have a wire test kit. I am not positive on this, but I\'m pretty sure. It sure sounds like it. Let me know how you make out.

What I found on the internet was that P1320 is a
transistor in the ignition coil, that turns on the primary
side of coil

Maybe a 1320 is similar to a Generic PO303
eg: coil #3 middle plug firewall side

You can put the P1320 into the computer & continue
on for the answer

Maybe a bad #3 cylinder coil, if the code actually
is accurate. On my Lincoln, even professional scan
tool software, isn't always of any use, sometimes,
because of coils not grounding properly & coming
back on the TPS Sensors

P0700 means transmission control fault detected,either it is mechanical or electrical.This code is a generic code,you will need a enhanced code that mean a manufacture scantool or a scan tool that can read enhance code.

You will need to have the the ECU scanned at Autozone or Advanced Auto Parts, unless you have an OBDII Scantool. Let me know the codes and I will tell you what they mean.
