THe car has no codes, it doesn’t turn on long enough to show any codes so I am ****ed

U sure your exhaust system isnt being blocked off by something?

i am not, but would that cause it to not start up? I had it installed the day before, I smelled burning rubber and was told it’s the new muffler smell while it breaks in.

Update. I have eliminated everything from the headers back to be of any problem. I removed them and the car idled no problem until I warmed it up then i gave it a rev to 5000 in neutral where it then stalled (I guess is the proper word). What could have made my car turn off?

ps it was so ****ing loud my throat got very uncomfortable I now think every neighbor hates me lmaooo

It wont start again? What happens if u slowly rev it up?

it starts, I slowly reved up to 5k where it just stalled

I’m giving up hope, expect to see this car parted out soon

ILl be wasting 150 for a diagnostic plus the towing there and back, plus the part and maybe even labor. This is why I am hoping someone would nail what it may be and save me some money, might as well replace a bunch of parts for less and do myself than waste on the diagnostic and towing and parts and labors. I really thought it would be something stupid and easy, how damn complicated can it be when we all know the problem and are limited to the fuel system being the culprit? I’ve already replaced the fuel pump, crank position sensor and starter. The car runs then when revved up to 4-5k it will die. Only other possible things I can think of is the fuel injectors or fuel filter. The car apparently doesn’t have a Throttle sensor so it can’t be that, I am pulling my hair on my 🥜 🎾⚾️

Hmm I really wanna know what the problem is now. Does it die exactly at 5K everytime? Does it die flat or does bog down bedore it dies?
