Thanks for the info the u1403 code is implausible fuel level the p 1037code is something to do with the O2 sensor the p code came up first before I change my fuel pump module when I changed my fuel pump module a couple weeks later that's when the u1403 code popped up my fuel level reads empty all the time with the gas light on but I have a full tank of gas I think it might be one of the wires on the harness that connects to the fuel pump module I think I might have accidentally pulled on some of them too hard and they might have came loose once again thanks the Jeep runs fine
