2003 No Power after sitting 21 years

[Lcaldwell]

I have the coral 007 2003 thunderbird. It has been sitting in my garage since I bought it in 2003. Only mileage is driving from dealership. But, since it has not been driven, now the electronic system is not working. It will not turn over when I try to crank. I have replaced battery, and still nothing. I have had one technician at a dealership to try and fix it but with no luck. If anyone else has had this problem, please let me know if you were able to get it fixed.

I updated your title "2003". How is anyone supposed to know what your post is about when all the title says is 2003?

Also why did you post this is parts for sale discussion? 🙄

When was the last time the car was started?

What do you mean by "the electronic system is not working? Is the car completely dead?

I am obviously new to this forum, and I am unfamiliar with exactly how to post. Sorry for the confusion. The car started fine about 4 years ago, but now everything is dead (even after changing batteries).

I would connect the battery for four hours or so, not do anything with the car, do not try and start. Then disconnect the battery
for about an hour, then reconnect let sit for about an hour, then see if the car will start or begin to power up. If not repeat over
and over a few disconnect cycles and see if car will start or power up.
The car has sat for so long most of the computer modules will not power up most likely because many of the capacitors have
lost all conductive properties, so the modules will not power up. Going through multiple power up cycles may allow the
capacitors to slowly come back to life.

You "obviously" did not read your welcome message or watch the video on how to post, OR the failsafe on-screen prompt where you typed the title that told you what to type for your title!

Apology accepted for not following directions, not being new. SMH.


With that said, if the car has been sitting for years, there is no telling what is wrong with it. Could be all kinds of issues including rodent chewing a wire.
