1990 vert,,,had 3 injectors put in,last thursday,,,picked up car friday,,running great,,,,went to movies sat. night witht the wife,,,after movie,,unlocked wife`s door (the gentleman that i am,,lol),,unlocked doors,,walked around,,i think wife relocked doors,,anyway,,alarm went off,,i shut it off with my key,,,,,,started car up, (battery voltage was normal),, in about 5 seconds,,car shut down,,,could not restart,,,sounded as if it wanted to start, but wouldn`t..the more i tried to crank it,,i could see battery voltage start to drop...friend towed back to mechanic,,,tried to start it this morning (sunday) again no luck,,could hear fuel pump..no codes have been pulled yet. .my question is, do you think this has something to do with the injectors? or can the VATS actually shut down the car... battery ??,,,just trying to get an opinion from all of you,,thanks,,,will keep you informed,,,
