Remove the air intake hose at the throttle body, clean the carbon out of the inside using a brush and a can of throttle body cleaner, do this with the battery disconnected after cleaning drive the truck for about 15 minutes and the idle should be back to normal.

Hello and welcome to FixYa!
As
a first course of action, I strongly suggest that you remove the
positive battery connector and let it sit for at least 5mins. before
reconnecting it. This will reset the system and can get your vehicle
back to it's normal operation.
Hope this helps and thank you for using FixYa! Have a good one!

There are several possibilities ranging from a defective starter, to bad cable connections, to the onboard security system locking out the starter relay, or an aftermarket accessory interfering with the starter circuit, or a locked-up/damaged engine.
I have had vehicles towed into my shop for similar complaints when the only problem was that the customer was using a cheap duplicate key that they had made at the hardware store that did not have the required computer chip in it.
I have also had vehicles towed in where the customer had replaced the battery and did not have good cable connections or forgot to connect one of the wires that was supposed to to get hooked-up to the battery connector.
Then there are the questions: Are you getting any kind of "clicking" noises when turning the key or is it completely dead? If it is clicking, WHAT is clicking? Is it the starter motor itself that you hear or just the starter motor relay? Do you have battery power at the starter "S" terminal when turning the key? If not, is the transmission selector in "PARK"? Does the shift indicator on the dash indicate that the transmission range sensor is in "PARK"? (possible defective transmission range sensor) Are there any fault codes stored in ANY of the modules connected to your onboard computer network?
It is really hard to say without being able to see the truck.
SOURCE: tundra won't start after ran out of gas
Your fuel pump is packed up and you should change you fuel filter as well its clogged
SOURCE: Engine wont start, unless I push the gas pedal and keep my foot on it.?
Could be a dirty throttle body, or a stuck idle air control valve.
Is the check engine light staying on now ?
