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+).
TEST 3: Jumpering the fuel pump Circuit. OK, so far you have confirmed that the fuel pump relay on your Ford car or pickup is getting power on wires labeled with the numbers 2 and 4. In this test step, we're gonna' jumper two wires (numbers 3 and 4) together to manually get the fuel pump to activate. Disconnect the fuel pump relay from its connector. 2  Locate the terminals labeled with the numbers 3 and 4. 3  Using a jumper wire, jumper terminals 3 and 4 together. 4  NOTE: Don't use anything that is too big to fit into the female terminals of the connector..
