The 6.0L is far from that, It is a very good engine that just needs a some care and maintenance by persons familiar with the engine.
The common failure in your current scenario described is the fuel pump itself. All you need is a good test light to test the current to the pump at the connector with it still plugged in. The way I do this is simply back probing the two wire connector with 2 (opened partially) paper clips sharpened on a bench grinder to make a fine sharp probe. Then from the wire side pushing in along side the wire slipping it in past the seal to contact the wire pin. Then placing the test light across the two clips turn the key on and you should have power for 15 seconds. If so you have a froze up pump and the whole module needs replacing. It is cheaper than the individual pump.
Let me know if you need anything at all further.
Give me a couple mins and I will get the layout pasted here.
OK here are a couple schematics showing the layout of fuel pump power routing. As you can see there are more than one fuse and more than one relay that control power to the pump, and usually like I said this is not the problem.
excellent thank you so much. I just tried the paper clips into the back of the plug as well as into the holes with the plug pulled out. The light (which i tested on a battery to make sure it was working) did not light up. I was testing the terminal that was vertical- not the horizontal plug which plugs right in next to the drain hole at the bottom. I am assuming that the bottom plug is for the water in fuel indicator. thanks again,
did you get the schematics ok?
