CEL (check engine light) PO462 intermittent problem recently changed fuel pump hoping this would solve gas gauge problem to no avail and even paid for diagnostic that didn't help other than the tech said there was 0 volts from the fuel pump going to the cluster and he said there should be 5 volts. They wanted to charge me more money just to pin point the problem and my impression was they didn't know how long it would take to do that.

HI there

If there isn't any reference voltage, then it's not going to allow the gauge to work. It sounds like either a broken wire or a problem with the new sending unit.
