Why wont a 2004 5.9 liter Cummings turbo diesel engine start after you change the fuel filter?

Answer 1

I'm not real sure about the smaller diesels, But you have to fill that filter with diesel before installing it! You may have done this already. Hope this helped! actually on the isb engines with a good working transfer pump. you turn the ignition key try to startthen release the key and wait for a minute or two while the pump fills the housing. if it doesnt do it the first time then just try starting again. repeat upto 3 times before checking to see if the housing has fueal in it. but ISb engine are noted for the transfer pump to die on you. if that is the case you can buy a oem from the dealer, or a after market from fass or I know there is another company. also if you have a transfer pump and a vp44 injection pump... might want to get a fuel pressure light or guage... I replaced to on my isb and finally bought a fass and the problem was solved...
