That normally means that you have a issue with your gas cap try replacing your gas cap first then diconnect the negative terminal of the battery for about three minutes to clear the memory and start the truck again

Remove the air cleaner and look into the throttle body and see if there is gas coming out both injectors.If only one is working then switch the wire connector from one injector to the other.This will tell you if the injector is bad or if it is not getting a signal.Check for good vacuum at a good vacuum port.Should be close to 20 inches of vac.If not then this could be a good sign of bad timing or plugged converter.Hope this helps.Good luck.

SOURCE: hello there, i have a
p0300 it means you have multiple missfires if you have a coil pack on this model it could be a bad coil or timing is off can do then same but usually a p0300 or example p0301 is a misfire on number 1 cyl as well p0302 and so on you should of stopped after plugs and wires this usally solves the problem or even the pcv valve now i would go back to the first step code p0300 they have precedures to follow but you do not have to replace the engine like they suggest maybe a simple compression test would show if the motor is sick but i would go back to basics and start new before going in head first
