Help Identify "rolling start?" Maybe injectors last leg?

[HOSS-06]

Hey guys,
Thought id see what you think about a problem that I'm having.

Couple weeks back I noticed when starting the truck it would seem to start almost cylinder at a time, rolling start, hard to explain exactly. At first every once and a while, now getting worse. Have to hold the starter on longer sometimes now as it fires a cylinder and then misses, keep holding until fires up.
When running everything is just fine, pulls hard, idles great, fuel millage the same, new oil, truck has 158k miles on it.

Any ideas what I may be looking at fixing in the short future?

I haven't done anything yet, . have just been driving it. just noticed it a couple weeks ago and it has not gone away.

Hoss I think I follow where you are going do you have a fuel pressure gauge? and a monitor? it could be anything from low fuel pressure to a bad FICM to injector sticktion,

Thanks for the response, Was acting bad today, Its embarrassing having it crank so long and burp before it starts when I'm out in town. I have had the FICM replaced 2 years ago so I hope that is not the problem. No fuel pressure gauge or monitor though. May sound dumb but if its low fuel pressure, does that just mean the fuel pump?

Usually means fuel pressure regulator, there is an updated fpr spring kit. $55.

You need to google ficm check procedure, thats my guess, with no other info.

Thanks for the info, I will do that test when the truck is cold.
Even though the problem is there when the truck is at full operating temp. That seems like an easy enough check to eliminate the ficm as the issue

Well, if it's doing it at op temp, check it there also. And it may be, icp sensor and or pigtail , hpop leak. There is a air test for hpop leak also, that will rear it's ugly head when the oil is hot. You need a monitor.

I have not had a chance yet to check anything, ill get to it this week.
But I was doing a lot of running around this morning, the problem was really bad, after it sat for the afternoon at the job it was fine, the problem is only there when truck is warm.
Seems weird.
