I am replacing the fuel injectors in a 2008 Duramax diesel... How hard is it to do? I was told that you had to pull the heads to do it. Any suggestions before I start?

Frog,I think anyone on here would be more than happy to help, however I think you will find little knowledge on the duramax on this particular forum. I would imagine the injectors are as hard to get to in the Dmax as mine were in my 6.0 SuperDuty, so yes, removing the cab is going to be the easiest. It was a miserable experience for me and I personally would think it would be easier to just sell it rather than replace injectors in it. LOL. Just poking at ya a little. Good luck.
