I'm not sure, but I think after replacing a battery, some car computers need to be sinked with
the new battery. If you have a service manual, check there. If not call the local Chevy
dealership and ask a knowledgable, knowledgable, service writer it that is the case and how
to sink it. On my 2014 GMC that is the case, and I'm not sure how far back that computer
feature went. Next,: Why was that battery changed? Just because, or for the same issue?
Did you test the old battery? Also if you let it sit for a while, you might consider hacking up
a trickle charger to it to keep the battery fully charged. If the replaced battery is not fully
charged, the computer will not start the car, but run the lower drawing electrical equipment.
Check the battery charge also. Then if that does not work, are you getting power to the
solenoid? It may be on the far outside, a computer sensing issue. Before pouring a ton of
money into changing parts that are not needing replacing, it might be better to tow it to a
very good mechanic, not necessarily a dealer. sometimes a good mechanic can fix it at less
cost, and the difference may be the cost of a tow. Check around, ask questions, and made
an educated decision.
