It is a highly complex vehicle, you need an auto electrician with a pro grade scan tool computer to diagnose what electrics aren't working

it's built into the transmission range selector

ballast is located in each headlamp assembly.

I assume you are taking about the evap system purge valve - the purge valve is located behind the EGR valve on the left side of the engine.

its located at the lowest part a crescent wrench will do the job but you must jack the car to locate it its at the bottom of the oil pan please block your car before climbing under your car good luck

The Pos. stud is the only one,the ground is to the engine itself ,
At an engine mount or on the intake,anywhere a clean solid connection can be made.

YEP BAD FUEL PUMP WILL CAUSE STALLING AT LOW SPEED DRIVING ALSO OVER HEATING ENGINE,STUCK OPEN PCV OR EGR VALVE,FAULTY IDLE AIR SPEED CONTROL VALVE,FAULTY TORQUE CONVERTER CLUTCH SOLENOID.I WOULD HAVE CAR CODE SCAN FIRST BEFORE BUYING A $500.00 FUEL PUMP.
