Car won't start
 

Car will start run briefly then quit. It has been sitting up at a transmission shop getting some work done when this happen. I need to get the car started and back home. I understand that disableling the "Vats" is one way to get around the security system but I don't know where to find this on HP tuners.
Any help would be appreciated.

I have same problem with 2002 z-28. manual trans. Had dealership change key and locks. changed clutch safety switch. Tried to reprogram security system. have to push start it all the time. Help

why does not ls1 motor start up,except push start battery, clutch switch ignition key help

Could also be a grounding issue. You could check all the grounds on and around the battery. They may have disconnected the battery if they worked on your car. Just an idea.
