Cleaned the MAF? Spark plugs? Coil pack? Vac leak? Knackered injector? Reset ecu?

Cleaned MAF but will do it again tonight.
Plugs new.
Coil packs replaced.
Vac leak not checked yet.
Injector again not checked but would it throw up a code?
Reset ECU done.
Quick bit of background fault code showed a coil pack down so replaced them all car started on button and run. I run it around the estate and it ran fine for a car which had been laid up for a year. After leaving it for a an hour or so I then tried to start it again and it would turn over but not fire up almost drained the battery but managed to get it going. Anyhow I thought plug it back in to code reader and it was saying 2 of the 02 sensors down so replaced them but its still the same if not a bit worse. Plugs I admit were a bit sooty when I pulled them last nigh but not over excessively so cleaned them and tried again. Car eventually started but it would not throttle up and if I blipped the accelerator it would just try to stop as if it was over fueling.
One thing I haven't changed but will do is crank pos sensor which I will this weekend.
Im still listening for any advice which you guys can throw my way cheers.

Ok an update. This is a funny one to say the least well I think its funny anyway. What I forgot to mention was I swapped out the fuel pump a couple of months ago thinking this was the problem but the car ran fine so thought all was well there and it was pump works a treat. Anyhow yesterday I thought I would have a look at the pump again to see if all was ok and it was working so I pulled it out again to see is if the filter was blocked. Filter was fine so popped back to shed for a cuppa and laid it next to my original pump that's when I noticed the level arm indicator was set at a different height. I believe that this has 3 settings you unclip it and move it up or down. The one I took out was set on a lower setting the float was hitting the bottom of the tank and telling me I had a quarter tank of fuel when it was bloody empty. Unbelievable.
Anyway after walking around the garden laughing like a drain I put my old one back in filled with fuel and it ran perfectly.
So just for ner ners why would the spare pump float be set at a different level I wonder anyone got any ideas?
Hopefully she will be off to garage for MOT this week and on road by weekend I hope.
Mark.

That is a funny, but we've all been there with different car related issues I'm sure.

Glad you got it sorted in the end though, and good luck for MOT. At least all the other bits are new and will future proof the ignition side.
