Engine/Transmission (1998.5 - 2002) Thanks to so many guage problem solved

[wrichards]

Posted numerous times about guages - tach, oil press and temp not working. 2 dealers told me different solution of over $1000. 00. Also one dealer told me it was unrepairable and to sell the truck wholesale. The solution was simple as usual. At the suggestion of members I rewired the faulty plug on the backside of Cluster. Still did not work but ruled out as culprit and TSB completed by me. I also pulled the Ecm plug, contact cleaned it and greased it. Still not solved. Finally I pulled all three PCM plugs and contact cleaned and greased them, fired it up everything working. The truck was a MA truck before I owned it and there is a bit of rust. I think A little corrosion got in there and did it in. Again Many thanks. After two months of time.
