you have to find out what you are missing,could be spark,fuel pressure,vacum,ect.can you verify that you have good spark to the spark plugs?these trucks have a lot of distributor cap and rotor issues.

what is the fuel pressure,have you checked it with a gauge?does it have a tachometer? if so does it move when you are cranking it?also pull the [plugs ans see if they are soaked with gas.

the ground would be a black wire at or near the fuel pump harness that most likely goes to the frame and is attached with a bolt or screw.
