I have this issue. My cooling fans had gotten where they would stay running after I parked it and running my battery down . Then also my fuel pump stopped working and then started working again. But the fans come on when I turn the key off and turn off when I turn the key on. Now I have no power windows or locks only half of my instrument cluster works my abs and battery light and check engine all stay on . I have checked every fuse that I possibly know of I don't know what else to do?
After the dealership replaced the sending unit in the truck the gas gage started reading full or empty nothing in between and sometimes it will throw a check engine code. Would the be in the fuel pump or would that be a problem with the computer I’m really looking for a place to start. Is there a place that i could run a meter to see what the problem is before i start tarring into things?
