To check basic spark get a spark plug tester from auto store for about $5. Remove fuelpump fuse. Remove spark plug, connect to tester. Have a buddy crank car an watch for spark. Do this for each plug. No spark is likely a bad ign. wire or coil. Be careful not to touch electrical wire/plug while cranking as they put out a lot of electricity.
after all that work its terrible that something else goes bad however since you do get spark and fuel i would say crank or cam sensor but then if one of those goes bad it wont allow engine to turn over and would shut fuel pump off. so there is only one thing left to cause it you have a short in the harness somewhere maybe just a lose connection on the cam or crank sensor put dieelectric grease in all your connectors
Turn key to on for 5 sec then off 5 sec then on 5 sec then off 5 sec then on 5 sec then off 5 sec then start. If start good = loss of fuel pressure. Probably the fuel pump if this is the case but could be fuel leak, return stuck partially open, leaking injector into the motor etc but likly pump. Let me know how you go with the on off test
My first guss would be a fuel pump, just would have to verify that when you first turn on the ignition to crank you can either hear the fuel pump turn on in the tank or not, if you cannot hear the buzz or whine noise from the pump in the tank you need a fuel pump. Fuel pumps are a very common problem with these trucks.
It's either not getting fuel or spark. Have you checked to see if you are getting any spark to the plugs. Take one of the plug wires off its plug and place it close to the frame or engine. When you crank the engine you should be able to see a spark jump from the plug wire to the frame. if you do not see a spark you have a problem with the ignition system. If you do see a spark then the problem is with the fuel system.
