This is a N-14 red top select 435 hp. Problem started about 3 years ago . If truck sat with out being run for more than 3 days it was hard to start. Engine would crank over for about a minute before starting, and if it gets below 50 degrees it won't start unless I plug in enging block heater. Now it has gotten progressively worse. I have changed fuel filters every oil change, new fuel line from tank to ecm. I don't see any leaks anywhere. And now everyday it starts hard. Sometimes 5 or 6 cycles of cranking it over for about 30 sec each cycle then waiting for about a minute and starting again. When I take fuel filter off it is about 2 inches down in filter. It acts like it is not getting fuel. It won't pop or anything, just like you run it out of fuel. Now what I have discovered is if i take plug out of intake manifold and pour about a 1/4 cup of diesel in the intake it will fire up in about 3 seconds of cranking and stay running. Can't figure it out, hoping someone can help me figure this out without a huge shop bill of someone parts changing. Please any help would greatly appreciated.
