My ‘02 6.0 won’t start

Plugged fuel filters on efi engi e's can do some bizzare things.  If you don't recall when you last changed it, it may very well be time to check it.  Surprised I didn't mention that, it's usually first thing I mention.  Perhaps GM moving them to the tank has made me forget about them.

I had changed it when I changed the fuel pump, which was almost 3 years ago. But you never know maybe something got in the tank. Worth a try I guess.

Back in the carburetor days, any customer having a fuel filter last 3 years was unheard of.  I realize filters are a lot larger, but they are pumping fuel through the filters many times more due to the pressure regulator just dumps fuel down the return line to the tank. That pretty much ensures all the dirt that is small enough to get past the sock in the tank, will get trapped in the bigger filter eventually.

I guess its all apart of maintenance. So to recap:
-check fuel pressure and spark when acting up
-apply a can of injector cleaner
-try priming pump a couple times before starting
-change fuel filter
-make sure air filter is clean

I think that’s everything! Thanks guys! I’ll give it all a try! [emoji16]
