Is it turning over?

Are the ignition lights on?

I don’t think an O2 sensor will stop the car from starting. Could easily be the ignition switch, but as said other than not starting what can you tell us?

Agreed, all those codes are O2 sensor related which aren't used at startup. If not turning over it eill be either starter motor (give it a tap with a wooden mallet) or the ignition switch.

Car is spinning over fine , started for a sec this morning lumpy and then died , when turned over now it gives a slight splutter but no start

Is the ignition switch a known fault ???

Easy fix ???

No, if it's turning over ok it's not likely to be either of those. I'm assuming you have enough fuel in, in which case fuel pump / fuel pressure related maybe. When did you last fill up?

When you switch the ignition on, can you hear the fuel pump priming as normal?

Tried turning on and off the ignition to check the switch and lights lite up everytime, sounds like the switch may be all right

Focusing on pump now , can you get at wiring in car to check for power , don’t hear it priming but can’t ever remember hearing it

I’ll jack it and have a look now

We can do better than this!
Accelerator pedal to the floor, hold it there, and crank engine. If it fires, let throttle go. Its a quick clear flood. Repeat once or twice.
If youve got any carb cleaner or wd40 or easy start, pop air cleaner lid off and squirt any of the above in while someone cranks. If it tries to fire, you have a fuel issue. If not, most likely spark.

Quick and dirty checks as a start.
Andy.
