Ok, so I'm a bit puzzled. I've got a '03 4.0. The fuel pump is good. When you turn the key on (koeo) the fuel pump doesn't prime. If you proceed to crank the engine, the fuel pump will come on and after a couple of seconds it will start and run as normal. No loss of power, stumbling dieing etc. Any ideas what would cause it to not prime before cranking?
