Replace the crank sensor as they get hot they will sometimes quit working. The temp light comes on everytime the engine is turned off and the switch is on. Next time it dies spray or pour some water on the sensor then see if it will crank and if it does you know what it is.

you probably need a blower motor resistor. its located in the heater core case under the hood. it may only be available with a new blower motor.

take off the wheel and remove the axle. knock out the bad lugs and press new ones in with a big vise or shop press

In the exhaust pipe before the catalytic converter

ok what u have to do is take the wheel of
and just simply hit them with a hammer as there set in by grooves you will see on the new ones the grooves
when u put the new ones on put though the hole and tightin up as much as u can
then undo the bolt put the wheel on and do them all up real tight with a rattle gun

A 90 Buick Regal Oil filler cap unscrews all the way out and does not "half-twist". It's just stuck. You may want to buy a replacement (about $4) before applying more force or tools to it, just in case it's brittle.

most likelly it is your fuel pump is not puting godd fuel pressure
have the fuel pressure test and if it is low have the fuel pump and filter replaced
