    I was driving home the other day and there was a lightning strike very close to me. The dash display fed from the computer went blank, including the info centre. Headlights , radio etc stayed on. I stopped the truck and restarted it and when I did the display came back but my analog gas gauge now indicated I had about 7/8 of a tank of gas even though I really had less than half a tank. It never moved for the next 20 miles but all else operated ok including fuel consumed, miles per gallon and miles left on the tank of gas? I filled up the tank and the gauge went to the over full position as it should. As the fuel was used the gauge again only went to about the 7/8 full point and stopped. The digital display for gallons consumed is working fine though. Any suggestions??
