Do you have any visible fuel leaks , any fuel leaking under the truck on to the floor ? Also try to get a scanner of some sort that can monitor actual rail pressure and see what that is while cranking

I just did my head gaskets in my truck which is the same year, It took about 5 times pumping the primer hard and about 2 minutes of cranking before it fired. I would post the codes and make sure you have everything plugged in, I had forgotten my MAP sensor and I thought it was a fuel issue too.

If it turns a couple times and stops setting isn't plugged in I bet. It should crank for a good 15 sec or so before it kicks out. Check your big bale connectors and make sure they are seated and also you should look and see if any of their pins slid out.

You will probably have to clear limp mode with a code reader,should be P0700, unhooking the batterys and cycling the ignition over did not help me.
