Wanted to see if any one could give me a quick hand. When the truck is first started, only does this on cold start, it sputters and hesitates to start up almost wanting to stall out on me. Its only on the first cold start when the truck has been sitting over night, after that its starts perfectly fine. Any ideas? Other than possible fuel pump, if that. Already did fuel filter and tried running a couple tanks of premium to maybe clear out any bad gas it may have had.

 

Plugs?

 

Just did those not too long ago.

 

Have you had injector issues?

 

negative. never had any issues up till now. Only thing i havnt tried either is running truck stock to see if maybe the programmer is the issue.

 

Give that a try.

 

Sounds like leaky injectors to me.
