Report: Engine Starts and Stalls Due to Secutiry System Fault
Chevrolet Impala Problem
Engines Affected: 3.4L V6, 3.8L V6
Average Mileage: 120,364 mi (35,000 mi - 236,772 mi)
The engine may start and stall with the security light flashing. This is commonly caused by a failed passlock sensor which is part of the ignition lock cylinder. A secondary cause could be the ignition switch itself. Worn contacts inside the ignition switch can cause voltage drop issues which can affect the passlock system. Proper diagnoses should be performed before replacing any parts.
car wont start due to no fire to the crank sensor and fuel pump

NOT STARTING and SECURITY LIGHT is problem--no problem with engine stalling
every month or so--SECURITY LIGHT comes on and stayed on for few minutes
6 months ago, 3 months ago
when key turned to start car--no sound--not start
all electrical devices work
wait---then start after 3 to 15 minutes--engine has NEVER stalled
then last week, not start, rotate through messages
3 minutes, 15 minutes later--still not start
half hour later, car started, but CHECK ENGINE LIGHT came on and stayed continuously each time engine was started
Mechanic charged retail to replace ignition lock cylinder $ 225.90, almost that much to remove and replace, plus diagnostic fee, and recoding and reprogramming fee

Car will not start and security light is on. Wait about 20 minutes then car with start. Keeping happening on and off. Then finally I have to buy new battery like every 6 months. Haven't repair yet, trying to find out myself if anyone solved this problem.

car won't start - security light flashes- get out of the car close the doors - lock it with remote - leave it alone - wait 10 minutes and try it again - took me 3 times of the car doing this before I realized to leave it alone - don't play with the remote ie: lock and unlock
