2001 Chevy Impala crank but not starting sometimes
Do you have a check engine light on? If so get a auto parts store to scan this and tell us which code or codes are present and get all the information from the employees doing the scanning too, Unless you know for sure the sensor it says to fix is cheap or has a problem for sure do not spend the money for it just now as the can be many reason a code can set that just affects that sensor while the sensor is good so those reason need investigated first, just let us know we will try to help.
I do not have an check engine light. About a year ago I replaced BCM and had the dealer program it, and everything has been good until about a month ago. Started having problems with the AC and information center not coming on then no power to the fuel pump. I was told it was the ignition switch, replaced that and it worked for a couple of days and now sometimes the fuel pump doesn't get power so it won't start just cranks.
