Super... do an internet search or search here on VATS, you'll find the system disables the car from starting. Never does it make it stall out.
Check your battery cables, including under the boots. We find this fixes about 9 out of 10 issues like this with spark and fuel being good.
If that'* not it.. we've also seen a couple other small things ...one being a crank sensor.
And if.. you want to triple check the security system, read up on the security light and how it is supposed to behave in it'* different modes. We'll get you fixed up...don't worry.
