No, a bad fuel pump will cause a no run situation.
Bad regulator
bad gas mileage
Yes
Yes, a bad O2 sensor would cause a 2002 Dodge Dakota to stall. It would also cause bad fuel mileage and hard idling within the vehicle.
In my 1999 Alero, it did this and it was traced back to the power steering pump going bad.
yes
Yes it certainly could cause bad gas mileage especially if it is plugged up or if your car's oxygen sensors readings are faulty.
Yep.
Putting your foot down too hard on the accelerator.
It could, yes.
