A few days ago I took the pic attached. Its important to know tgat the truck was not running. It ran that way for a good part of that day. I also had an incident where the needle for the tach gave up and was hanging alnost straight down and that happened while I was driving. It went back to normal when it didn't work while driving after I stopped for gas but the picture incident didnt clear out til next evening. Any ideas on what is causing this? What I dont need is this possibly affecting other gauges and end up getting stranded without gas. Thanks.
