Assuming all things are still as they were when you started this thread.
Here is a link to a code interpreter. http://www.dakota-truck.net/CODES/codes.html
The codes you reported 45, 37, 32, 27, 51
Did you fix or resolve the trans codes 45 and 37? 32 EGR code even if the EGR is not working won't affect it much. Ralph's advice is good.
I'm looking at the 51 code as the problem now. This describes it and offers the O2 sensor as one possible source http://www.allpar.com/fix/codes/faults/code-51-52.html
Also the description of code 51 on this page indicates low fuel pressure may cause it. I don't recall whether or not you resolved the fuel pressure issue. http://www.dodgeram.info/Engine-Gas/...fault_code.htm

Based on this I would check the O2 sensor to see what it looks like and make sure the fuel pump is delivering consistent pressure at the right PSI.
I am still getting 37 and 45. Those are trans codes. The truck is a 5 speed so the plan was to ignore those 2 codes. The egr is not super important for me to figure out. I do not need to pass emissions.
I have not gotten the 51 since i changed the distributer pick up and rotor.
When I do the key dance I am getting code "27" 3 times.

didnt read the whole thing over again, but I KNOW that code 37 is nothing to do with your issue.
