I have a 05 5500 engine light has been coming on for the past two months and no one has an answer. Have replaced 5 fuel filters and the fuel pump and regulator also found a fuel line going into filter housing that was rubbed real bad and replaced it but still nothing thanks in advance

how many miles?

Check the injector return rates. At this point that's about all that is left, faulty injectors. 15 seconds of cranking should net you 12mL of fuel.

Yes truck puffs blue smoke all the time

Ok I haven't had a chance to check the return rates but had to travel to New Jersey today Iwent out and started truck and engine light was on decide to baby it and not let it go above 2000 rpm and after about 15 or 20 mins light went out and it never smoked any thoughts.
