PO 123 Throttle Position Sensor Circuit High Input
PO 223 Throttle Position Sensor Circuit High Input
Probably two different switches on the sensor. I'd say get a new Throttle position sensor. Try starting it with light pressure on the gas pedal, if it satrts it's definetly the TPS.

the sensor to replace is the HO2S sensor which is different to an O2 sensor. (has a different function)
code p0300 is random/multiple misfires
as misfires are from the electrical components you did not pay attention to items like low fuel pressure and faulty injectors which also cause random misfires.
then scanner will show a code (po**** or p**** or a series of dots and dashes) You then have to refer these codes to a manual for interpretation of the faults. ie code on scanner p0707 . refers to TR sensor switch and a number of possible causes that will cause this code.. With out a scanner you cannot read any codes
P0300 is random multiple cylinder misfire and P0316 is misfires detected on start up. This is an ignition related issue. I would check the ignition system and tune up condition and proceed from there also if you have access to a sanner with live data capability check that you have and RPM reading when cranking the engine and the times it deosnt want to start this would indicate an issue with the crank sensor
battery should be showing 12,45 - 12.6 volts when car is standing still. also batteries getting old colects sulphate on plates ,this degrades the cold start performance. you can see that cranking amperage on stickers of batteries. for example 90 amperes 750 cca battery is required for my car but les wont crack it even it is 90 amperes but 640 cca. mainly lead acid or dry type batteries needs to be charged more than %40 of its capacity. 12 volts is only the ~%25 of its capacity and it seems yours is dead already.
Forget the PO316 and 1st 1000 Rev,that is a Ford thing
No other PO Codes? PO 305 for cyl #5?
If you have individual coils (COP Ignition )
one is bad. Last number of a 300 code is the cyl
maybe. Unless it is really bad,then get back here
for more help
Sounds like you may have an issue with the check valve on your in tank fuel pump. When these go bad, you have to crank several time to build up enough pressure in the fuel rail for engine start. With a good check valve, the fuel pressure will not bleed off and the pressure is retained for the next engine start.
