Can the truck start up with a jump?
If the truck can start with a jump then check the voltage at the battery posts.
After warm up (10 minutes), it should read 13.8-14.6V

Some part store can do a diode check on the alternator for internal defect/short/bad diode/ripple voltage.
Check for spark on the plugs.
With key on (do not turn),listen for the fuel pump rotation noise.
Check the fuel pump relay or security system fuel cut off
Make sure you hooked the starter cable to the positive terminal on the new battery. If it is, then tap the starter, maybe the solenoid is stuck.
