You have a Cadillac! You can assume that the thermostat is bad, the intake manifold is leaking and that you have a connecting rod or 2 going bad. Caddy engines do not last without constant maintainance.You can spray water on the intake while the engine is running....if the noise goes away, you have a leak.Jim

air bag should reset on there owen if not you have bigger problems

First thing I would do is to determine the fuel pump is actually still operating. Sitting for so long the moisture inside the tank may have corroded the pumps internals, when you switch on your ignition , have someone lay near the tank to hear if the pump engages and makes a whirring sound untill it pressurizes the lines. If that is ok I would disconnect the fuel filter, air compressor to blow through the lines after removing the valve on the fuel rail and fit a new fuel filter, once it is done ensure that you have fuel pressure up to the valve {in fuel rail end} Test the fuel pump also by placing a catchment bucket under the fuel filter, remove it then turn on ignition to see if it pumps fuel. might pay to also pull out the plugs and wire brush the rust off them. hope this helps.

Did car run out of fuel? If so yoou may need to get rid of air lock. There is a fuel rail on the top of engine with a valve on it like a bicycle tire. With key on, remove cover on valve and push it until fuel comes out. This may solve the problem. If not you may need to loosen the nuts at injectors to allow air to escape. Also caused by fuel line leak.

Did you check fuel pressure at the injectors with a gauge before and after replacing the pump ?

I will say you have a faulty headlight switch, That switch works in phases as you turn it on each click operates another set of lights.
