tanman Posted May 27, 2023 Share Posted May 27, 2023 Where to begin troubleshooting this? I put a new tank in a month ago. Same sender. Everything was good until yesterday. Link to comment Share on other sites More sharing options...
Gary Lewis Posted May 27, 2023 Share Posted May 27, 2023 Pull the wire off the sending unit and ground it to determine if it is the sending unit. If grounding it works then the sending unit has to be bad. Link to comment Share on other sites More sharing options...

FuzzFace2 Posted May 28, 2023 Share Posted May 28, 2023 Did the water temperature and oil pressure gauges stop working as well? I had a new sender stop working after a short time. Grounding the wire showed the gauge still worked for that tank so was not the switch. Come to find out the float filled with fuel and sunk so no reading I replaced it with the old one and been working for years now.
