ok they are 1698- Fuel Temp to high, 1899- Fuel temp sensor B circuit mal, 1487- Fuel Delivery Error. I just checked the fuel pump and yea it does prime and then once i let it prime i went to see if i had pressure im my fuel rail and it blew out a lil bit of air just a lil. fo you think it could not be pumping right or the fuel filter is clogged?
