08 sierra hard starting

[dirtdriver11]

I got an 08 sierra with the 6.0l.  Replaced fuel injectors and mow the truck cranks awhile be for it starts. I can cycle the key a couple of times and give it partial gas and it helps some. It didnt have problems staringbefore replacing injectors. I have replaced spark plugs. Any ideas?

Check fuel pressure.

I replied on another forum,stay here,more help,so, partial gas,to me,means rich,you are leaning it out?

[dirtdriver11]

How?

[riverbanks]

Any fuel odor,out tailpipe? Wondering if c.t.s is not connected properly,or lean?

[dirtdriver11]

Not that I have noticed. What is c.t.s.?

[riverbanks]

Coolant temperature sensor,was there anything you are sceptical about on reassambly?did you install orings dry or lube them?

[dirtdriver11]

Lubed o rings. Everything went together fine. I have been having this problem for a month or so. Normally I would think fuel pressure unless it is just a coincidence that it happened after replacing injectors.

Should do the fuel pressure test,nice to know where it's at,you could disconnect MAF electrical connection,see if that helps, sometimes no info is better than bad info
