DaveBen is correct, if the batteries and starter can't spin the motor fast enough for it get the oil pressure above 550PSI on the HPOP side of the oil system the truck will never start. Optima batteries are a female dog to charge if you are not using the correct battery charger to charge them and I've personally experienced this because I have Red Tops in my truck. To fully charge the batteries in my truck it takes over 5 hours to get them charged enough to start the truck. It's going to take a lot of cranking to get the truck to start if there was no fuel in the fuel rails.
Check the fuel bowl heater fuse to make sure it's not blown because that will also cause a no start if I remember correctly.
