I hit a deer on frt driver side of my car. Upon impact my car shut off but fan was still running. Tried to start it and nothing. Fan runs all lights on dash on, everything works. Take car to nissan dealership ecm had to be replaced. Now car cranks and it'll start but instantly die. Technician told me gas was bad he needed to clean the gas tank. Day before I hit the deer I pit that gas in my car. No issues at all until I hit that damn deer. Now I owe dealership $2500 and car wont start I dont know what to do, PLEASE HELP

 

Bad gas is plaisable. I would also check for things that got dislodged or sucked into the imtake. The sound generator may have come loose causing a lot of air to bypass the maf. But, i am only speculating here.

Do let us knnow what the real fix is. best of luck.
