Alright so this really has me lost so a few days ago the car wanted to spudder and not wanna go so i had to pretty force it home it would fire up and idle fine but second it got intoo gear and move it died slowly died and rpms would go crazy. So i managed to get it home roughly and not it's parked k been replacing stuff all night and still can't figure it out i have no codes at all. The battery been unplugged during the part replacements and hasn't ran so i think the no codes is from that cuz I should atleast have egr code due to removing that years ago. But any ways TPS and connection, CAS and connection, MAP, and Crank sensors are all new. I determined having spark after all this by removing the plugs and seeing spark and u had spark and could hear it too. Put them back in the block tried cranking nothing just kept turning over my pump is ruunning yes so its not that maybe injectors I sprayed starter fluid in the engine tried cranking and poff a cloud of white smoke outta the intake nothing got damaged that I can see and I'm still on time and its still turning over BUT now no spark.. back to just turning over and over again whats causing this please
