Hey ya'll, been lurking around here forever but decided to finally make an account cuz my car is broken and I'm totally stumped. Cars a 2005 S with no mods.

So I burned a valve almost a year ago and put a new head on myself, car ran great for awhile and then developed a misfire. I assume it was due to the coilpack or some other part of the ignition system because it would only really happen under heavy, sudden load. The car ran fine otherwise and I could even floor it with no misfire it if I rolled onto the throttle slowly enough. I didn't have money at the time and it wasn't too bad so I just drove it easy and put it off. Fast forward to last week, and the misfire was getting worse and then it finally wouldn't start. There was no 'event' or anything I just came out midday after driving it earlier and it wouldn't start. I replaced the coilpack and it still wouldn't start, so I did the plugs and wires today because they were corroded and I figured that contributed to the issue. No cigar, it tries a little harder to fire over than it did before but it still doesn't quite get there, and I have no idea wtf to do now.

As said in the title its throwing a P0302, P0313, and P0300 codes, I reset them all and no change. Anybody have any idea what I should be checking next? I'm really hoping I didn't burn another damn valve. Sorry for the lengthy post just wanted it to be clear what I was talking about. Any help anyone can provide would be a godsend. Thanks ya'll.

 

P0313

Try looking at the code definition. It might just be out of fuel.
