The most common cause of this problem on the Impalas is their @$!@ security system called Passlock or Passlock II. It is very sensitive and senses an intrusion a lot of times even when there is not one. When it does it locks down the fuel injectors. You can leave the key in the ignition in the on position and wait 10 minutes for it to re-set but it tends to do this 4-5 times a month at a minimum. The way to permanently solve this is to disable this portion of the system.
You will need to take the dash off ( it is not as hard as it seems) It is held in place with a variety of bolts, screws, and clips. You can do a web search for dash removal to try and find the exact configuration. Once the dash is out under the steering column there is a metal plate. It needs to come out also (held in place by a few bolts. Once this is removed you will have clear access to the underneath part of the steering column. Coming up the steering column you will see (3) wires grouped together. (Yellow, Black, and White). They will either be tied or taped together. The only one you need to concern yourself with is the yellow one. This is the most important step. (1) Start the car! (2) While the car is started snip the yellow wire, making sure it does not contact any metal. (3) using electrical tape or something similar cap off the ends and tie it off if you wish. (4) Turn off the car, put the plate back on, the dash back together and problem solved!. The yellow or orange security light will stay permanently illuminated, but it is not a problem. I did this on my Impala which I inherited 10 months ago and have never had this problem again. You can take the bulb out of the instrument cluster to for the security light but it is a lot of trouble and not worth the effort. Hope this helps..
