It's been an on going thing with the truck shutting off when driving or when I turned the truck off it wouldn't start back up for about 45 min. To an hour.I had it to the dealer twice and they couldn't tell me. The problem wouldn't happen all the time. It could be twice a week, twice a month or twice a year, so by the time I would get it there the truck would be running and they said they can't find nothing wrong because the problem is not happening now. So I started trouble shooting myself. When the truck would act up I check for fuel or spark, had spark no fuel. So I started at the fuel pump relay, replaced that and it ran fine for a while. Then it happened again. So I put my shop manual in the truck and test light in the truck and waited for the next time. When it did I probed the relay plug and it was fine and when it came to unplugging the relay when the truck was running that's when I found that the oil press switch was bad.
have the same problem?
