A nonsense mutation in the leptin gene that results in a stop codon and lack of leptin production was first observed in mice in 1950. In the mouse gene, arginine-105 is encoded by CGA and only requires one nucleotide change to create the stop codon TGA.
The fuel pump relay, located deep inside the TIPM, is the most common relay to fail since it's powered on 100% of the time while you're driving. You likely found this website because your dealer wants to change your fuel pump ($600+) or TIPM ($1000+).
When the key is turned to the on position the relay is switched on and power is directed to the vehicleâs ignition and fuel system components, notably the fuel pump and ignition coils. When the relay fails or has an issue it can cause major problems with the operation of the vehicle.
