truck won't start :(

[Eyegore]

I learned this from a mechanic:
Set parking brake!!!!!!!!!!!!!!!!
Have someone get in the truck, then in in park or netrual, have them turn the key as to start, then you, under the truck lightly (lightly) tap the starter with a small hamer, if it engauges replace the starter solenoid or the whole starter. If it does nothing then you may have cabeling, ignition and or battery problems.
