2005 Ranger Fuel Pump Cuts out after 1-3 minutes
My 2005 6x6 started cutting out after a few minutes of operation. It dies, and then when you turn the key back on, no fuel pump. I checked the voltage to the fuel pump and found that it was fine (it ran fine when the relay(?) applied voltage) I started gathering more information and began to suspect that the problem is temperature related (it runs longer before cutting out on a cold morning then a hot afternoon). Then I realized the radiator fan isn't coming on. So I jumpered it and found the fan was fine. Next I found the engine block temperature sensor (?) just below the carburator. The jacket protecting the two wires was worn through. I couldn't see any copper, but I ran out of time and will take a closer look tomorrow. I can't figure how these wires, if shorted or open, would cause this behavior, but its all the information I have at this time.
Has anyone seen this pattern before and know a solution? Any help would be much appreciated.
