On the rear of the head,drivers side, beside valve cover.
I have the idiot light so it is a small sender,don,t know size of the guage type sender.
Usally P/F .put to ground,guage should work.

Wayne, are you sure your information applies to a '96? I don't have one and never worked on one, but '96 was the first year for the new OBD-II computer. It was my understanding that with the new system the gauge was controlled by the ECU and that the head sender/sensor was no longer used.
I don't know that this is the case, just asking.

Wayne, I do have a small sender in the position you described. It has a single wire from it that I have grounded. The guage does not move. Should I try a different guage? Thanks again.

Jim,
"Test the circut by grounding the wire to the sending unit while the ingition is on (motor off).If the guage deflects full scale,replace the sending unit"
leave the wire on the sending unit and use a jumper wire to ground it,The guage in the cluster is replaceable,but that is a lot of work.
Did you have any other electerial problems? You may have burnt up the printed curcit.
Try a new sender first is what I would do.

Tested the sending unit as per instructions above. Still nothing. I do not have any other electrical problems. Had the dash apart and check volts across screw heads marked TU & GRD. Voltage was 12.8 with key on and 13.6 with engine running. Thanks for all the help so far.
