Tried the key in door, nothing. Should & how do I reset the Security on car ? Car has done this twice before & after replacing starter relay was fine but now nothing, still won't start

When I try to start it I have to have my foot on the gas peddle or else it just cuts out. But once it is started it drives and stops fine without cutting out. What do you think the problem could be?

I have a DHS which is not listed in your options.
Air bag light and message on DIC center reporting check air bag, very intermittent.

No air flows in front dash or defrost but it is ok in the back..When driving what air that comes in through the vents does heat up or is cool..Could this be the resistor motor?
