Did you change the correct sensor? Your engine has 3 temp sensors, one for the light, one for the gauge, and another for the cold timing/fast idle.

I changed the one on the drive side closest to the oil fill tub which I found on a labeled photo on line showing where all three were located. so as far as I know I changed the right one.

Okay, sounds like you got it.

Try pulling the wire from that sensor and grounding it. Turn the ignition switch 'on'. If the gauge is functioning properly it will peg or close to it on the hot side and the new sensor is faulty. If there is no to little movement then the gauge or wiring is faulty.
