Hello and welcome to JustAnswer!

U1412 is a vehicle speed signal issue and won't be related to the no start condition.

The no start could be a handful of things including the starter itself, a cable or connection issue, low battery voltage, an engine mechanical issue; one of the most common things I've seen on these is voltage drop between the starter solenoid terminal and wire at the crimp.

Are you getting a rapid clicking that happens the whole time the key is held in the crank position?

hi, thanks for that and no it's a slow clicking.

Expert:  sprinkles08 replied 2 years ago.
Is it a single click that happens each time the key is turned to the crank position, or does it continue to click while the key is held?
Customer: replied 2 years ago.

it continues to click.

Expert:  sprinkles08 replied 2 years ago.
You most likely just have a dead battery then. I would recommend trying a jump start (not always reliable ),swapping in a known good battery, or having this battery load tested.
