Hey yall i have a 2004 sxt that ive had for about 3 years and have put about 50k miles on.

For the most part it has been a good running car until about a month ago i got a code about the cam sensor being bad so i replaced it.

While replacing cam sensor i was doing other maintainence checks and must of forgotten to screw the radiator cap on all the way and the ol lady took it for a drive and let it overheat.

So since it overheated i changed the thermostat and it ran fine for about a day(100miles). I went back out to start it and it wont turn over and thats how it stands today.

I first noticed a p0129 barametric code so i replaced map sensor. No change.

Now im getting p0335, p0430 along with p0129. Not sure where to go from here.

All the research ive did keeps pointing to maybe the timing belt being off. Is this something i can check myself with an obdII reader? Or how do i check how far its off? Im new to all this so im confused by the most basic mechanic talk so if someone is patient enough could maybe walk me through this. Much appreciated

 

If it won't turn over, the battery is dead.

 

Sorry thats not what i meant to say. It turns over, it just wont start. I had a buddy testing for spark as i was turning it over and its not gettin spark
