Have a 99 express 1500 with 5.7. Service engine soon light came on but no codes found on code reader? Also fuel gauge id stuck to far right, moves ever so often but moves crazy when it does, is it my gauge?

Oil change or other scheduled service due?

Intermittent wiring connection from the sending unit or the sending unit beginning to fail.
