Your pedal could be going back all of the way but the brake light sensor might need to be adjusted. There should be a pin to keep the axle centered.

It should be threaded somewhat or grooved to where you can adjust it out and in. I had to do mine awhile back.Let me know if that works.

As far as the wait to start light flashing, it could be that your grid heater is trying to cycle after the truck is running. Not too sure on that one all of my panel lights have never worked.

Flashing for a fault, only time I've had mine flash is when my intake temp sensor is unplugged, may have a faulty intake sensor.

You should take a real good look at the spring leaves themselves for cracks or even broken leaves. That is a pretty typical result after that stuff starts coming apart.
