Alright this isnt on my bronco, its on my brothers 89 f250 with a 351 and a C6. He went mudding the other day and when he got home and shut the truck off it wouldn't fire. It would crank and get spark. No fuel at Schrader. Checked fuel filter and made sure pump was good. We found the fuel pump relay was bad. Bought a new one, put it in, fired right up. Shut the truck off and the fuel pump wouldn't shut off. Got another new relay, same thing, worked fine until we shut the truck off and the fuel pump stays on, any ideas??? Thanks alot guys.
