Dude, SLOW DOWN!!! I understand your impatience, but throwing money at a problem is only for people with more cash than sense. Did you try the starting fluid again? I'm guessing no? If you're going to buy stuff, I would have bought a set of noid lights and checked for injector pulse, but that's in the past now. You could still buy a spark tester or just check it the old fashion way by putting a screwdriver in the boot and holding it close to bare metal on the block. I'm not sure the old plug method you used is the best way. If you still get no spark, and your power and grounds are good, it most likely going to be a crank sensor issue, either the sensor or mosf likely the wiring from it. Know anyone with a good scanner or tuning software you can use to see if the PCM is seeing RPM during cranking? Also, are you absolutley sure you're not loosing power while cranking? Some circuits are hot in 'run' but not during 'crank'. To test this, turn the ignition on, and then jump the solenoid at the starter. MAKE SURE THE TRUCK IS IN PARK AND CANT MOVE SHOULD IT START.
