The reason is that it is 18 years old, it is a Chevrolet (GM) and it is an Impala as described here. https://www.vehiclehistory.com/report/chevrolet/impala/2005 'All of a sudden won't start' is terribly vague, turns over (cranks) but doesn't fire, just a click when you turn the key, or nothing at all? Your best bet is an auto electrician and your issue is electronic. A professional grade scan tool computer can diagnose in 20 minutes. It is far better than guessing components, swapping them out and finding it doesn't fix the problem. https://www.google.com/search?q=mobile+auto+electrician+near+me ..

Question edited for typos. Question moved to model category. So you turn the key and nothing happens, no click, engine doesn't turn over, nothing? You know 'cranking' is turning over? If the engine doesn't 'fire', it isn't running. There is no such thing as a 'crank relay', you mean the starter relay or perhaps the starter solenoid. Call out a mobile auto electrician. They can hook up a fancy $5,000 scan tool computer and diagnose this in 15 minutes. It is electronic, maybe the immobilizer. https://www.google.com/search?q=auto+electrician+near+me ..

Question edited for clarity.Question moved to model category.Wow, that is cold for Texas. It probably has the original transmission fluid in and it is gummy and thick. The filter is probably blocked because of the cold and the shift solenoids are also sticking because of the temperature. Start the vehicle and let it tick over until it gets to normal operating temperature, then try again. Get to a transmission shop and have the transmission filter cleaned and new transmission fluid.

You will need a full set of metric and imperial sockets for any work on vehicles. You don't need an impact wrench. Videos that show the job. Basically, you jack the car up and sit on stands or blocks. You undo all the mounts and you raise the motor to get the mounts in.

How often do you actually use the key this way when the car is running properly? If you rarely use it, over time the tumblers inside the lock get dirty and damp. This can make them 'sticky' and difficult to move. Dose the lock with releasing fluid and leave if for 30 minutes. Reinsert the key and work it in and out while wiggling it side to side. Do this for at least a full minute. Dose the lock again with releasing fluid, leave for another 15 to 20 minutes and repeat the 'Wiggling' method. BE PATIENT! It's a pain in the tailbone repair and can take some time to do.

Hello. It seems your vehicle has a 'shorting/malfunctioning turn signal switch and/or 'grounding' wires in the wiring harness. Good luck and keep me informed; if you want to.

Hello. The air conditioner 'low side' port is in the engine compartment by the right front wheel. The 'low' side is the only port 'freon' (R134A) will 'connect' to. Good luck and keep me informed; if you want to.

Check your 60 amp fuse in the underhood fuse box and see if it is good.

Probably bad spark plugs, wires or ignition coil. Also cylinder number one spark plug is prone to cracking. If you cant isolate a cylinder pull each plug out and inspect for carbon tracking or plugs worn. Recommend using AC Delco original equipment replacement spark plugs.

possible 1st and 2nd trans solenoid or fluid/filter

DTC P1631 Theft Deterrent Fuel Enable Signal Not Correct The powertrain control module (PCM) controls the fuel injector operation and the starter operation based on a vehicle theft deterrent (VTD) password from the vehicle body control module (BCM). When the ignition is first turned ON, the BCM sends a programmed theft deterrent password to the PCM. The PCM acknowledges the password and responds to the BCM that normal fuel injector and starter operation will continue. If the PCM detects an incorrect password, a theft deterrent system failure, or an attempted vehicle theft, DTC 1631 will set. The engine will not start or crank as long as the condition is present. Diagnostic Aids DTC P1631 indicates that the vehicle theft deterrent password that the PCM has learned does not agree with the password received from the VTD system. This condition can occur if the BCM has been replaced and the PCM Password Learn function has not been enabled. If the BCM has been replaced, the password must be relearned. Step Action Yes No 1 Did you perform the Diagnostic System Check - Vehicle? Go to Step 2 Go to Diagnostic System Check - Vehicle in Vehicle DTC Information 2 Perform the Password Learn Procedure. Refer to Programming Theft Deterrent System Components . Did you complete the procedure? System OK 30-Minute Learn Procedure Turn ON the ignition, with the engine OFF. Attempt to start the engine, then release the key to ON; the vehicle will not start. Observe the SECURITY telltale. After approximately 10 minutes, the telltale will turn OFF. Turn OFF the ignition, and wait 5 seconds. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes. The vehicle is now ready to relearn the Passlock™ Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK. Important: The vehicle learns the Passlock™ Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. Start the engine. The vehicle has now learned the Passlock™ Sensor Data Code and/or password. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles.

Could be any number of reasons why this happens . The headlamp switch , the dimmer switch the headlamp relay , the BCM - body control module , wiring , connections , ground etc..... Without testing no one on here could say for sure what's wrong . Do you know how to test electrical circuits ? Viewing wiring diagrams then using a DVOM - digital volt ohmmeter to test the headlamp electrical circuits . Possibly hooking up a scan tool an checking headlamp switch input data to the BCM an seeing if the BCM is energizing the headlamp relay .

During ALC the low beam headlamps are on for daytime running lamp (DRL) operation in daylight conditions or low beam headlamps and exterior park lamps on in low light conditions. The DRL/EXT Fuse in the top underhood junction block supplies battery positive voltage at all time to the coil side of DRL relay, left low and high beam headlamps. The EXT LTS Fuse in the top underhood junction block supplies battery positive voltage at all time to the right low and high beam headlamps. For normal manual low beam operation when the headlamp switch is placed in the HEAD position, ground is applied from G203, through the low beam contacts in the headlamp switch to the body control module (BCM). The BCM then applies a ground to the headlamp relay control circuit. This energizes the headlamp relay in the left I/P junction block allowing ground from G201 to be applied through the switched contacts of the headlamp relay, through low beam contacts in the headlamp dimmer switch then to the left and right low beam headlamps, illuminating them. For high beam operation the headlamp dimmer switch is placed in the HIGH position, ground is then applied from G201 through the switched contacts of the headlamp relay, through high contacts of the headlamp dimmer switch to the left and right high beam headlamps, illuminating them. When the dimmer switch is placed in the HIGH position, the indicator lamp input to the BCM is pulled low. The BCM then sends a class 2 message to the instrument cluster in order to illuminate the high beam indicator lamp. If the headlamp switch is left in the HEAD position, the inadvertent power control feature will turn off the headlamps after 10 minutes after you turn the ignition switch to the OFF position. If you place the headlamp switch in the head position after the ignition switch has been turned OFF, or if the ignition switch is in ACCY position, the headlamps will remain on until you turn them off or until the battery runs dead.

Sounds like either something is jammed in the seat track and/or the track has to be replaced and that is a complicated operation there as I have replaced a number those. everything has to go back exactly as it came out or you have to take it out again and correct it and that in itself is no fun. Like I said, it may just be something jammed in the track but also, it could be a broken seat motor drive shaft and in which, the seat track or more commonly referred to and "seat module". That should be left to someone who has ahd experience in replacing them because they can be very tricky. I hope this helps you, Jesus loves you, John 3:16-17 (KJV)

may have blown a fuse or relay

Fan as mentioned, but can be a fuse, or fan speed control. If you can get to plug on fan can feed power and ground to see if it runs. Common for the speed control to go bad. Some models have a ceramic block with a coil in it. The coil consumes power to allow slow speed fan meeting. They get hot and burn up.

Hi, There are two types of fuse boxes on the Chevy 2000-2005. An internal one and an exterior one. If you go to the relevant web site, you can watch a tutorial. I hope this helps.

If it overheated and warped the cylinder head, that would cause a no start. Do a compression and leak down test to see if the head gasket is damaged.
