Hey, truck in discussion is an 89 D150 with the 5.2. I had the water pump off to replace the gasket, afterwards the temp guage stopped working. I replace the temp sending unit with the proper senor for the guage. I checked the new sensor in hot water and resistance changes, installed without any tape or anything. If I ground the connector with key on, guage will peg, also cleaned inside of connector. I'm stumped?
