DP Tuner, no digits

Hey, need some help, haven't used truck in a week or so, went out tonight to start it up and noticed I had no green numbers on the tuner, so I have no idea if i'm on 1 2 or 3, and truck wont start, any ideas?

I would check the connection on the tuner and then the chip and if no go i'd call/email dp

edit: From their support article

Turn on ignition of truck and while you are turning on the ignition to the “run” position, watch the chip switch display. Does a small dot appear in the lower corner of the switch as soon as you turn on the ignition and then go away immediately OR does no dot come up momentarily and the chip switch does not light up at all with the key on?
If a dot appears in the lower corner when you turn on the ignition then the truck is in NO START or position 0 and this is why it will not start. With the ignition turned on, press and hold the left button (-) for 3 seconds and let off and switch should reset to number 1 and truck will start.
If not dot appears in the lower corner of the switch when you turn on the ignition and the display does not light up at all then there is no power to the switch, which means the PCM is dead or the install was done incorrectly.

Thanks Jason, I have checked the connection on switch, it's good, I also do NOT see a DOT. It seems strange that the truck was fine a week ago when I last started it.

When you turn your key do you see the WTS light?

I'd do a continuity test on the cable from the chip to the switch. If I pull the switch off my F5, my truck will not start. Sounds to me like an open circuit on one of the wires to the switch.

If you pull the tuner completely out, off PCM your truck should start, it puts it back in stock mode.
