Posted to GM Driveability on 3/31/2009 16 Replies

car can in on a hook, has no spark. scan tool showed RPM all over the place while cranking so I changed out crank sensor. still no start and then found that readings on scan tool were jumping all over the place. injector signal will go from none to super fast....
