I'VE GOT A THAT STARTS EVERYTIME YOU TURN THE KEY, BUT SHUTS OFF 3-5 SECONDS LATER

1996 Buick Regal • 154,000 miles

We got a new key for it and a new ignition coil for it in case the connections were bad too but the problem still continues. The security light stays on and the check engine light is on. I know if the computer isn't seeing the engine running, it won't run the fuel pump, but how do I check the Cam and Crank position sensors so I'm not just throwing parts at it. Also could it still be a security issue? And how do I check that?

If the security light is on its a security issue Get a scanner and read the codes let me know the exact code numbers not code descriptions.
