Car won't start
My 2016 Chevy Malibu won't start. Car sat in
storage not running for 7months. Now I try and
start it and nothing happens. Key fab opens doors
but nothing else works. Radio works with jumping
cables hooked up but nothing else happens
Sounds like the battery has been completely dead for a while. You should pull the battery and take it to a parts store for a charge and test. A full charge may help. With a 4 year old battery, it is very likely that it needs to be replaced after being dead for months.
That’s right you need a fully charged battery before proceeding, after that the security system needs to be reset and that information is in the owners manual. Another day Robles that happens to late model vehicles is if the main power is lost it can corrupt the BCM’s programming, if this has happened the accessory’s might not work or if they do they won’t work right. Unfortunately the only place that can re-flash it is the dealer.
