I'm having trouble with my truck. I didn't drive it all weekend then I got in it and it was dead. thought the batteries were dead. hooked jumper cables up to them and it still wouldn't start. the gauges in the dash are bouncing all over the place and you have to play with the clutch pedal to get it to even turn over..and when it does it turns over slow.. any ideas? started maybe? it has 162,000 miles and I doubt that its ever been changed..
