2007 Pontiac Grand Prix. The pulley on power steering came off along with belt. Can pulley be put back, or do I need the whole pump?

Question edited to add full make and model, plus spelling (pullEy). Question moved to sub category. Yes, they are sold without a pulley. You have lost the bolt from the end that holds the pulley on. You can see in the images here. https://www.google.com/search?q=2007+pontiac+grand+prix+power+steering+pump .. ..

2007 Pontiac Grand Prix. Why does my auto door locks keep blowing a fuse when shifting out of park?

You need a good auto-electrician. Something in the shifter is causing that fuse to blow. It must have some shared power. Your doors work fine. Take the control apart and check for chafing, and check all the way down to the transmission. https://fuse-box.info/pontiac/pontiac-grand-prix-2004-2008-fuses-and-relays ..

Will Vaseline lock the engine if you prime the fuel pump with it on a 2007 grand prix

There is no need to prime the pump with anything on a 2007 Grand Prix. The pump is submerged in the fuel tank and will push fuel to the engine without priming.

Pontiac grand prix 2007 car shutting off, with Start disabled throttle control module.

It doesn't say module , Starting Disabled Due To Electronic Throttle Control ! The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions: • Accelerator pedal position (APP) sensing • Throttle positioning to meet driver and engine demands • Throttle position sensing • Internal diagnostics • Cruise control functions • Manage TAC electrical power consumption The TAC system includes the following components: • The APP sensors • The throttle body assembly • The powertrain control module (PCM) Normal Mode During the operation of the throttle actuator control (TAC) system, several modes or functions are considered normal. The following modes may be entered during normal operation: • Minimum pedal value--At key-up, the powertrain control module (PCM) updates the learned minimum pedal value. • Minimum throttle position (TP) values--At key-up, the PCM updates the learned minimum throttle position value. In order to learn the minimum throttle position value, the throttle blade is moved to the closed position. • Ice break mode--If the throttle is not able to reach a predetermined minimum throttle position, the ice break mode is entered. During the ice break mode, the PCM commands the maximum pulse width several times to the throttle actuator motor in the closing direction. • Battery saver mode--After a predetermined time without engine RPM, the PCM commands the battery saver mode. During the battery saver mode, the TAC module removes the voltage from the motor control circuits, which removes the current draw used to maintain the idle position and allows the throttle to return to the spring loaded default position. Reduced Engine Power Mode When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions: • Acceleration limiting--The PCM will continue to use the accelerator pedal for throttle control, however the vehicle acceleration is limited. • Limited throttle mode--The PCM will continue to use the accelerator pedal for throttle control however the maximum throttle opening is limited. • Throttle default mode--The PCM will turn off the throttle actuator motor and the throttle will return to the spring loaded default position. • Forced idle mode--The PCM will perform the following actions: - Limit engine speed to idle by positioning the throttle, or by controlling the fuel and spark if the throttle is turned off. - Ignore the accelerator pedal input. • Engine shutdown mode--The PCM will disable fuel and de-energize the throttle actuator.

Runs great but going up a hill at a slow speed,, as I accelerate it kind of jumps and jerks or hesitates than kicks in what might be causing this? Plugs ?

A great place to start is the plugs and wires. This is a very common symptom of a tune up being needed.

What is wrong with this 2007 pontiac g/p no p/s at low rpms?

The power steering pump has nothing to do with it . Variable Effort Steering System Description and Operation The Variable Effort Steering (VES) system or MAGNASTEER?® Varies the amount of effort required to steer the vehicle as vehicle speed changes. At low speeds, the system provides minimal steering effort for easy turning and parking Maneuvers. Steering effort is increased at higher speeds to provide firmer steering (road feel) and directional stability. The Electronic Brake Control Module (EBCM) controls a bi-directional magnetic rotary actuator located in the steering rack and pinion. The EBCM varies the steering assist by adjusting the current flow through the actuator to achieve a given level of effort to steer the vehicle. The VES system accomplishes this by adding or subtracting torque on the input shaft to the rack and pinion. The main component of the system is an electromagnetic actuator, which consists of a multiple-pole ring-style permanent magnet, a pole piece, and an electromagnetic coil assembly. The VES system uses the ABS wheel speed sensor inputs to determine vehicle speed. When the EBCM senses wheel speed, it commands a current to the VES actuator that is most appropriate for each speed. The EBCM commands current from negative two amps to positive three amps to the actuator, which is polarized. At low speeds, a negative current is commanded, which assists steering. At medium speeds no current is commanded and steering is assisted by hydraulics only. At high speeds, a positive current is commanded, which creates steering resistance. Ignition voltage and ground are provided through the EBCM. The EBCM has the ability to detect malfunctions in the actuator or the circuits to the actuator. Any malfunctions detected will cause the system to ramp to zero amps and steering will be assisted by hydraulics only and setting a DTC. Your best bet is take your vehicle to a GM dealer or a ASE certified repair shop that knows about this system .

I need to find out how replace my power steering pump in my 2007 Pontiac Grand Prix

Fairly simple process. Remove serpentine belts, disconnect hydraulic hoses from the pump and unbolt it from the engine block and bracket. If the replacement pump does not come with the pully you will have to move it to the new pump.
