It was the Crankshaft Position Sensor. The brake fluid turned out to be very worn. It took almost a week and a declaration by the mechanic that the car was possessed, but he finally found the cause of the problem. Probably either a relay or the switch in the steering column. This other Chevy dealer decided to replace it and charge me for another repair and parts. Sometimes the chip is moulded in plastic and sometimes it is possible to take the key apart - in that case you should be able to fit the chip like a grain of rice to your new key.
Did you maybe get some adhesive on the thermostat preventing it to open fully? I researched to see if this was a common problem and was surprised on how many incidents were reported. As you can imagine, the trade in value was painfully low. I go to start it and nothing. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. Front seal of transmission blew on the highway. Clouds of smoke and long trail of tranny fluid. Looking at a wirng diagram to see what if anything these have in common ,power feed , ground etc.
I can start it up again and drive off but the same thing repeats itself. Had spark plugs, filters, fluids, tps sensor twice , crank shaft sensor and ignition module changed. At times my car would not start so had to put in neutral and park back and forth till it started. This happens almost everyday now and I am beyond fed up. I had a similar problem with my 2000 Impala.
Engine Cooling problem 2001 Chevy Impala 6 cyl Front Wheel Drive Automatic i put a new 195 thermostat and coolant temperature sensor. If none found, check for power supply at one side of the injector with the key on. As the key came from a different car it will need recoding. The other thing may be the water pump. There must be a heatsoak problem that affects the ability of the sensor to relay data to the computer. And my blinker was out, so I got pulled over.
Car has left me stranded and late many times. The problem happens alot when it is hot and humid, but can also happen at any given time. Nothing noticeable before windows dropped. I believe the computer is shutting the car down. Car immediately restarted but time on clock was wrong. I could find no mechanic or electrician who could diagnose the problem.
If I wait 10 minutes it will start. Vehicles that are covered by recalls 08V-118, 09V-116, or 15V-201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number. It scared the daylights out me, never had this problem before. Drivers door window won't go up. Needed new transmission 2 hours away from home. Anyway, I believe if you change the Crankshaft Position Sensor the problem will go away. Radio and lights continue tol work.
Note that the number of problems reported for the 2001 Impala is 803 while the average number of problems reported for the 23 model years of the Chevrolet Impala is 511. Replaced the wires to the battery. The temperature gauge's needle sits little lower than halfway mark and sits at little over halfway mark when I drive for a while and stop at a light. I checked for voltage at the right rear light. No voltage was present but I had a good ground.
There is no warning as to when this will happen, one day it happened 4 times. The security thinks the car is being stolen. The turn signals on the vehicle also do not work 50% of the time. Line was replaced and reattached. I work nights I cried because of being stranded in the middle of the night alone.
A month later, I was leaving a grocery store when I tried to start my car and it wouldn't start. Was leaking fuel, could smell it in cabin. My air-conditioner would no longer cool. This problem occurs on a regular basis. The brake lines were flushed and refilled which seems to have fixed the problem.
