Is the check engine light on when the engine is running?
This can sometimes be caused by a faulty mass air flow sensor or a dirty air filter. If it's been a while, check the air filter to make sure it's not plugged up. If it's not, then I would have you try unplugging the mass air filter and see if the truck will start and idle on it's own. This will make the check engine light come on, so don't be alarmed. We are just running a test. If it will idle with the maf unplugged, then it's the likely culprit and should be replaced.
This is the sensor that is mounted in the air duct work from the air filter up to the throttle body.

Well, it may not want to drive properly with the maf unplugged. It basically regulates the fuel mixture so the computer adds the proper amount of fuel. I would not drive it long like that, but a short time should be fine.
