Well this seems like a classic immobilizer problem except that the car doesnt have one... So i got this car a while ago and this has been an issue ever since i got it home. Went to pick it up and it was fine, test drove it etc. Then this. Ill let the video do the talking. Replaced ignition switch and crank sensor already.. Its like its just running normal and then someone just cuts spark all of a sudden. VR6 engine start problem: http://youtu.be/k-3f3JYamtc
