Default Code 51 twice

Good day!! i read the forums a lot!! thanks for the help that they provide...
i just recenlty fixed the odometer by using the forum. Thanks again

On my 91 dodge 318 4x4 i just checked the codes and found a couple of them im looking into:

my list
12 disconnected battery
33 i have no ac
37 park neutral switch?
than i get code 51 twice - on the truck it does smell rich after warm up it does looks like it has a new o2 sensor ,.. so after a bunch of googling and searching the forums
what would cause the 51 codes?
thanks in advance

Low fuel pressure, or bad O2 sensor, or clogged fuel injectors.
