I just put on a new fuel pressure regulstor which is under the upper intake plinum on the 4.3 vortec motor and started it up anfd it had white smoke comming out the tail pipe I then took it for a drive to see if it would clear up cause it seemed to be running good besides that anjd it ended up dieing and then it would not start up again after that
