Joe,
Thank you for your prompt reply.
You requested as much information as possible so here we go:
I've rebuilt the inside of this engine approximately 5 years ago it's got between 80 and 90,000 miles on the engine. I do not think there's anything wrong with the timing chain. However, within the past year I have had to replace replaced the outer engine accessories ignition coil, wires, spark plugs, fuel injector, airflow mass sensor, idle control valve, throttle position sensor, ignition switch, purge valve, engine coolant temperature sensor, product pressure regulator, camshaft position synchronizer sensor, crankshaft positioning sensor by the crankshaft next to the wheel with the 32 teeth, the fuel pump, anti-theft light bulb was out replaced it it's back on, wire was burnt off of the knock sensor replaced it
I am getting power to my coil, but I am getting no power to my wire or spark to my spark plugs. I have tried testing and starting the truck with starter fluid it will not. When cranking you can clearly smell fuel, so I know the injectors are working. Testing my coil with my multimeter set to 20K my results are 1and 6 gave me 12.40, 2 and 5 gave me 12.46, 3and 4 gave me 12.42.
Checking for resistance using my ohm setting all of my pins registered a 1.5, checking for continuity all of my spark plug wires registered 0.00 which I'm led to believe means there's no breaks in the wire.
Not sure how to check my PCM for power. Attempted to scan with my Creader VIi+ but because the battery was disconnected and then reconnected, I'm not showing any codes currently.
I have power to all items listed below:
Alternator, air flow Mass sensor, throttle positioning sensor, fuel injectors, idle control valve, power to engine coolant temperature sensor, fuel pump (I can hear it run and the pressure is between 59 and 60), knock sensor, purge valve, power to the starter relay and it is cranking over. Power to the crankshaft positioning sensor reading on my multimeter in the DCv is 1.5 the truck is off. With my multimeter set on AC while cranking my multimeter registers 2.5.
I am getting compression off of 1 2 3 4 5 6 cylinders anywhere between 150 to 190.

I do not know what these wires correspond with. Not real handy when it involves the wiring of a vehicle.
I would greatly appreciate any and all help you could send my way. Hopefully the information above gives you some idea why my truck is cranking but not starting.
