When I turn the ignition over the truck starts for less than 1 second, enough to where the RPM's get to about 400 or 500 then it shuts down. Good amps, full tank of gas. I pulled and reinstalled the ignition relay, starter relay along with other misc fuses earlier today and was able to get it running again. Got it home in the garage and had the same problem. I don't have a computer to check the code but the service light flashed 5 times then showed the battery symbol in red. Any suggestions.

It is probably the pass lock module resistor.

I would swap out the fuel pump which go out all the time in this truck, here are the instruction in the images below to show you how to do the job. Drain the gas out first, this video will show you how.
