1994 Pontiac Grand Prix SE 3.1L V6 DOHC Vehicle cannot be shifted into Park or First Gear. What could be the diagnosis?

If you can't move the shifter into PARK OR FIRST GEAR manually I would say you need to adjust the cable shifter. Try to move the shifter while someone looks at the transmissions cable underhood and see if the cable move normally and not out of the adjustment lock. 1- At the transmission end cable unhooks the cable from the transmission. 2- Try to move the transmission's selector manually from Park to D1. 3- If you cannot move the selector then your problem is inside the transmissions. 4- If you can move normally the selector then you have to adjust the cable.

Why am i howing trouble filling gas tank for a 2001 pontiac grand prix what can i do to fix it

Check the filler neck for foreign objects like a piece of syphon hose.

Be carfull when using a light around fumes though.

Or they also have a piece of hose which connects filler neck to fuel tank which could be collapsed or kinked.

2007 Pontiac Grand Prix when parked if I open trunk a while later the trunk will pop open. Lights flash.

Is this an aftermarket key opener. ? The brain box for this unit is some times mounted behind the left kicker panel by the left foot of the driver. And they get wet from foot water ie snow. Rain. The yr of ur car sounds like this unit could be water damaged. Have a look. Is u see green stuff allover the contracts thats ur issue. As well some times older cars remote fob controller is not isolated from other sigs. Ur truck does it only pop open when parked in one location ie home or work u might be picking up a similar radio req as ur button for truck lid as they have different radio freqs to control different things

Can traction control drain my battery?

Traction control cannot drain your battery. Once the car starts it is running off of the voltage supplied by the alternator. Traction control only activates when the car is in motion. As for the hard start..check your starter. It may be on its way out and pulling more voltage to start then the battery can supply especially when it is cold. As for the bucking it could be anything from timing to plugged converters to a bad sensor. For that you need to put it on an analyzer

I had to break into my 2005 pontiac grand prix because my wife lost the key and i was checking to see if she locked them inside. now with new key starting disable due to theft system

They key is not programmed... The car is reading the transducer and it is not giving off the correct code to the computer to start the car. The key has to be programmed. If you have the other original key you can try this. Use the original key , turn ignition to on, let set for about a minute. Take the key out and immediately put the new key in and turn to on then to start. The car just may program the key for you without going to the dealer. Good Luck.! Remember you must have one of the orginal keys to do this.

When my car is idling or I come to a stop it is chugging, when I accelerate it is fine. The RPM's drop to just under 1000. This just started, I thought maybe bad gas, but filled up with High Octan

Could be a variety of systems, however I would suggest the following first: Don't waste money on High Octane fuel or injector cleaners. These have very little to no impact on performance anyway. Idle Air Bypass or Idle Air Control Valve. You can often test this while at idle with AC off. Then turn AC on to determine if the RPM or idle changes. If no, then suspect the IAC valve. It can be bad or just be very dirty (ports blocked). Remove, clean and replace to see if that helps. If you see a lot of carbon buildup, then get that all cleaned up. If this does not help, then replace with a new one and go from there. Let us know, then we will try something else.

Learning how to test these systems an learning how they are suppose to work before replacing parts is what should be done , an if you don't know how you should take it to a qualified repair shop. The Temp sensor is an input to the PCM - engine computer .The PCM turns the fans on by energizing three relay's .Hooking up a factory scan tool that can view sensor data is how we do it at the dealer , Plus scan tool has bi-directional controls . I can energize the cooling fans with the scan tool ,check for DTC'S - diagnostic trouble code's .Turning on the A/C would cause the PCM to turn on fans on low speed . Free wiring diagrams here http://www.bbbind.com/free_tsb.html Enter vehicle info year , make , model an engine size ,. Under system click on engine , under subsystem click on cooling fans . Click the search button then the blue link . Relay Driven Dual Cooling Fan Diagnostics

08 grand prix have power fuel but no spark when turned over

My first thought with a GM 3.8 is control module, this can be removed and taken to any good parts store and tested, that said could be any number of things from a coil pack to a camshaft or crankshaft sensor, but after over 25 years in the automotive parts business, control module would be my first thought. Good luck.
