If you have the spider fuel system, it is noted for problems. I have seen bulletin about poppets sticking causing a problem with cold starts. After you get it started, if may do fine the rest of the day. The fix was cleaning the poppet valves. The cleaning procedure was a shop procedure, they use the cleaning mixture under pressure.
I doubt if using fuel injector cleaner in the gas tank will help. Just my opinion.
Because the SECURITY light is a warning indicator for the ant-theft system . If the light is lit the PCM - engine computer disables the fuel injectors an or in some cases the starter . Your best bet have it towed to a qualified repair shop .
