The gauges are doing a self check. What happens when you turn the key. Is there a clicking noise. Or one click? Do the lights go dim inside the truck when you turn the key. More info please
Check the fuel pump relay or the fuses. Could also be a filter near the injection rail. You might have a fuel cut off swithc. I don't know where it would be, but your owners manual would tell you. Good luck anyways.

Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. If that dont work try a different key do the same thing. This relearns your key to the ignition it started with Gm cars and trucks from 1999 to to 2006. It is a big problem but there is no recall that I know of. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys
The current from the battery to run the cabin will amount to about 20-30 amps. The current required to start the engine is 150-200 amps. Suggest fully charging battery and check to see if it will start. If o/k then check charging with voltmeter. Volts at battery with engine running should be 13.5-14.5 . If not , alternator is not working. PS make sure battery connections are sound and check all fuses. Let me know if this helps. Moe
