As a first course of action, I strongly suggest that you remove the positive battery connector. Let it sit for atleast 5mins. then reconnect it again. This will reset the system and can recognize the key fob again.
Hope this helps and thank you for using FixYa! Have a good one!
Based on the information provided, it may be the catalytic converter. Your car is exhibiting some of the symptoms. Another symptom is extreme heat coming from the unit which can usually be felt through the floorboards. A trip to the muffler shop for a free check would be the next place to go. If the CC checks out fine, you could have any number of issues including a bad computer, plugs, wires etc.
You have to take the whole brake unit off the disc. Usually two bolts holding it to it's mounting. Fit the new pads to it and put it back on. You will have to force them apart to fit them over the disc. Should not need to bleed the brakes. Make sure the bolts are tight.
Hello: If you are talking about the battery in the key fob then yes, there should be a slot in the glove compartment that you can insert the key fob and it should work. If you are referring to the main car battery then no, you will have to charge, jump or replace the battery.
put the new radiator in the car,forget about the sealant,that is for a temporary fix. You can buy sealants that can fix some head gaskets without taking the engine apart,you just have to follow the directions that come with the sealer to do it right the first time.make sure you refill with quality antifreeze after you get done.
I assume it has a push button for the fuel door. If so then look at the latch that the fuel door grabs on to see if it is broken or stuck on open. If stuck push on it a couple of times and spay it with penetrating oil to loosen. There is other possibilities but let's start there for now. I hope this is helpful.
Check first for leaks by using soap suds over the lines for the high and low of the AC system. An obvious sign of leak is oil coming out of the line or valves or at the AC compressor itself. If there are none then start the engine, set the AC and blower to high and connect the pressure gauge (make sure you have the dual one for the high and low so you can address both at once) and start adding freon.
If you only have a single gauge, have it connected to the low pressure side. See video below for additional reference.
sorry but the 2000 STS does not have a reset for the fuel pump. you will need to run diagnostics on the fuel pump system to find why it is not working, the first thing to do is test for a 2 second power pules to the fuel pump when you turn on the key if there is then replace the pump, if not then it is time to start running some tests on the control circuits.
