Could be leaking fuel injectors, they leak till the line pressure drops and then the engine is flooded. Overnight the gas evaporates.

well if my truck leaking injectors overnight it would have problems starting in morning but cranks right up the morning time is the best time it cranks my security light is on an stays on when i drive down road as well i heard something bout pass loc or something like that

It cranks right up because the gas has evaporated overnight but the security light could also be an issue. Do you have more than one key? If that doesnt work, it could be the sensor on the ignition switch that reads the key.

well i have a spare key an i also have key with clicker lock an unlock button

Maybe a defective fuel pressure regulator?
