430 Not starting, seeing bad battery symbol?

Your battery tender still plugged in?

 

You are probably hearing F1 pump

If the time has reduced substantial then you may have some issues with the F1 system

You should time him many mins pump stay off with key in on position
How many seconds (as accurate as possible) it runs with key on engine off after period it was off
How many shifts from n to 1 to n do you get

 

Yes ..I realize that but I was addressing your other concern about short pump cycle
If not a concern ignore my post

 

So my car, an 05 f430 starts with the tender plugged in. I never realized it wasn’t supposed to. Why do you think that would be? It’s an aftermarket tender if that matters.

 

are you using the under dash port? Pretty sure it only works with that

there is no better feeling than thinking you have a major problem with this car and it turns out it was absolutely nothing!

 

I think it’s only on the 07-09 (?) cars with the under dash port.

 

Yeah I’ve never been real clear if it’s the years or if that was an option

 

The charger is attached to the battery with a pigtail. It routes out from under the footrest.

 

Well that would explain it.
