**No crank at all/nothing/nada when key is engage to starting position

Could be the starter, starter relay, park and neutral switch/transmission position switch and ignition switch assuming the battery condition and connections are good. Note:If it doesn't apply disregard.

Recently installed 91 Octane tune with sct tuner car ran fine for a day was very pleased with the extra power. On the next day car started ran fine most of the day until I was driving home car started idleing funny and started bucking and backfire. Got wrench light on dash not check engine light. Parked over night started next day it had trouble holding steady idle tried driving it but wouldn't go more then 5mph kept stalling and kept bucking when it was driving. I returned car back to stock tune but the car won't start now. It's kicks over and immediately stalls.

Try resetting security sytem first if no manual look online. Then scan for codes to see if there is a problem. If this is a keep plugged in tuner to aldl then remove it as they will cause problems while plugged in and driven.
