My truck will start up and run good and sometime I tern it off and try to start it and it will just crank. Come to find out when it does not start my fuel pump is not terming on and I checked my fuel pump and it is good. But does not do this all the time

Sounds like you are losing fuel pressure. Check your fuel pressure when it is not cranking. The pump may be coming on but not building up pressure. Check on the link on the left side of the screen First Things to Check and see how to read and check fuel pressure.
Fuel pressure specs
2.2L 41-47 psi
4.3L vin Z 9-13psi
