A week ago I was driving my truck in fourth gear and my truck died out on me , presses the gas the rpm went up but I went now where , then I lost all power. The truck did not want to start for about 15 minutes . Finally it started up and got me home . Left it for a week , started up this morning and went to school. Now school is done but it doesn’t want to start . The truck cranks , but refuses to turn over . Any ideas what could be wrong? Fuel pump kicked the bucket?
