okay something new, I have correct pressure in the gas line. But while I was at the gas pump this weekend I went to start the truck it wouldn't say a word. So I tried it a couple more time and it starts up. But the thing that gets me is I had the radio off (after market) and when the truck start so did the radio. this truck Is a big puzzle to me.
mine was doing the exact same thing awhile ago, found out it was the starter.
