the other day i took my 03' 6.0 to the local lube station... got the auto tranny done, front + rear diff, transfer case and engine... i also got the fuel filter(s) changed, which is where my problem lies... on what im told is the lift pump (infront of tank along frame) where the one filter goes, it is dripping diesel out from around the black cap the filter goes inside... im guessing there is some type of seal or o-ring that goes there that could have possible been broken... how ever i don't have a socket that will fit it so i can remove the cover to check...
but now to the problem, since i got it back it takes for ever to start, and when i turn the key to the "on" position to get ready to start there is a weird grinding noise that sounds like its comming from the front of the engine compartment, it does it every time i turn the key from the off position to the on position, and then when i try to start it it takes a long time for it to fire, my friend and i were discussing it yesterday and we think it may be the lift pump (where the filter is i explained earylier) is bad or it is sucking air around the cap of the fuel filter... i remember reading some where that the powerstroke has a unique fuel injection system that is high pressure and either 10,000 PSI or somthing, so i figure with the high pressure injection system like that even a small air leak could cause a huge problem...
this is my first diesel vechicle and im not to familiar with how everything works... if the lift pump is bad, im thinking of going with a fass fuel, glacier diesel or another type of aftermarket lift pump...
fix the fuel leak first. you are probably losing prime on the fuel side. its a 36mm hex and yes there is a oring on there. if a quick lube did it, you probably have the wrong filters in it anyway so you may want to get the right ones and do it yourself.
