Sorry, I didn`t mention, I did those things first. On the wiring diagram I have for this truck, the gray wire supplies the hot to the fuel pump. There is nothing at the pump, (on the tank), but, at times, I`ll turnthe key on and here the pump come on and then it will start and run for a few minutes. You can here the change in the way it is running just before it konks out. Then when you turn key on there`s no electric at the pump. This has happened several times. Possibly a ground?
