Question about 2001 Chevrolet Impala

Open Question

The temperature gauge does not work and the air conditioner now does not work. Over the summer, the temperature gauge occasionally did not work and the a/c would not work during that time. I replaced

The vehicle appears to have had a police vehicle package on it at one point. Some extra wiring here and there and brackets in the engine compartment. The gas gauge has not worked correctly during any of this time. It will usually read full once the car is running most all the time. It will occasionally fall between 1/4 and 1/2 tank mark when the assumed level of fuel is in that range. The gauge will usually go back to the full mark at times before refueling. I have had the vehicle for about 6 months.

SOURCE: 1989 Chevy Truck 350 Stalled Wont Start After I filled Gas Fuel

You need to check the fuel pressure to the TBI. I just fought one which was doing the same thing. I pulled the fuel tank to replace the fuel pump. It turned out to be the short hose from the fuel pump to the steel line coming out of the tank. It had a split in it so I wasn't getting enough fuel pressure. Some places show two pumps available. One you can pull the unit and replace just the pump. The other the pump and sender are all one unit. Hopefully you have the first one. The second is around $300.

The easiest way to get to the top of the tank is to pull the front 6 bolts mounting the bed and loosen the back two. Take the three screws from the filler neck and unhook the rear axle vent tube. You can then take an engine hoist and lift the front of the box. You can get right to the pump and gauge assemble in the top of the tank. Most times, this works easier than emptying the fuel tank and removing it.

SOURCE: fuel gauge

khooper, in another forum, told me that "Chevron Techron Fuel System Treatment Plus can remove harmful sulfur deposits from the sending unit and a filmer agent that can prevent the deposition of said sulfur"

My 05 Trailblazer LT 2WD.
Erratic readings, and when the fuel level was below 1/2 full, the needle would sit on "Empty" with the amber light staying on.

So I went to a dealer, they replaced the fuel level sensor (p/n 19177712 SEN KIT 3.107 $118.62) with labor $270.00 for a total of $398.86 this appears to have fixed it for now.

I also talked to another mechanic who blames ethanol for these deposits !

The level sensor is bad. They are easy to do. You don't have to pull the fuel tank down. There is an acsess hole in the trunk. Look in the rear of the trunk at the rear of the seats. You will notice there is a spot in the middle that the capet comes together, Pull them apart and there is metal plate with some 10mm nuts, pull that off and your fuel pump is there, remove and replace the sensor.
Also there will the a code in the pcm. you will need to clear it to pass emissions

SOURCE: 2001 chevy silverado 4.8 gas gauge not working properly

Fairly common problem with GM vehicles. The sending unit in your tank has a small circuit board that an arm is attached to which moves up and down according to your fuel level. This circuit board and arm are not making good contact. Unfortunately the only good solution is to replace this part.

Testimonial: "thought probably that was it but better off replacing whole unit .i was for for gauge proplem thanks. "

SOURCE: gas gauge malfunction and engine light stays on

This is a common problem with Malibu's. It is due to cheap metal in the fuel gage that corrodes. Chevrolet knows about this but they refuse to issue a fix. The check engine light staying on and the faulty fuel gage are related. This is a defect and they need to recall this part! Raise hell with the dealership!

check for a bad earth in the system . Possibly the earth strap on the motor or dirty battery terminals . IF the temp gauge will not work (bad earth ) and the ac stops working ( cabin air temp reaches setting) or the circuit has an earth problem switching off the ac. Check all wires for broken , not connected properly and check each earth point for clean and tight.

Will not restart


Sounds like vapor lock. This is when the fuel turns into a vapor before reaching the engine (it needs to be in a liquid form). This is usually due to high temperature from the engine and environment. I would have someone check it out.

You might want to see if it might be low on 134a . Testing gauge can be bought at any auto parts store. Always check your a[c ounces ratio first. Auto parts store can do that. Refer to instructions for proper use. Use proper tools when working with things that are under preasure.

Air conditioner wont turn on


It might be the fuse for the AC compressor. Check to make sure the blower motor/fan is working by putting it on heat, or vent and adjusting the level from low to high (not temperature). Fan speed. Hope this gets you started.

Cd player console


I am a volvo s40 owner myself.
Try to eject all of the CDs at once. To do so keep the eject button pressed for a few seconds. this will eject the CDs one by one.

The temperature of the air conditioner is probably changing because of the outside temperature change. eg if the temperature outside is 35C and you set the temp inside at 25C it will come out cold air. if the temperature outside drops to 30C the air will come out hotter. you will notice that between summer and winter. the same temperature set will give either cold or hot depending on the weather.
in winter if you set it at 25C it will be very hot. In summer it will be cold.
