2007 6.0 Hard Starting

Over the last week I have noticed that when I start the truck it has started cranking really fast and takes a little longer to fire. up until the last week it has always cranked slower and fires after a few seconds. Today in a walmart parking lot it wouldn't start at all just crank really fast with nothing.... maybe it doesnt like walmart.. lol I was stuck there for 20 mins and almost called a tow truck when it fired on the last try. my mind drew a possible connection with this and the change in the way its be starting lately... any sugestions. I use a good brand additive on every fuel up and pay the extra for the high end deisel from shell. I'm hoping that maybe it was some bad fuel and i'll be able to work through it. I poured in some diesel 911 before i shut it off tonight... we'll see what happens in the morning

ok... so a little update. I seem to only have the ssue starti the truck when the engine heats up. when it's cold (ie. in the morning) it starts fine. I don't know what this means because while running there ar no issues and the temp gauges all read fine.

well for other people having this problem or just curious, I did a little more research and have come to the conclusion that it's the dummy plugs. when they start to go it explains all the problems im having and a whole list of other issues that i havent seen yet. hot start issue = problem with high pressure oil system

sounds like a high pressure oil leak. could be multiple areas. stand pipes, dummy plugs, o ring on top of the injector to name a few. best way no narrow it down is to supply air to the oil rail thru the icp sensor hole. sometimes you can hear which side of the engine is leaking so you only have to tear that side apart

so i got it back from the shop and they said nothings wrong with it... it seems to be running perfectly now. i guess we will see how long that lasts for... you never know, maybe it was an isolated incident.

I would NOT take that for an answer. Mine did the same thing and I managed to drive it around for two weeks just because all my timing happened to be just good enough to let the oil get cool and thick before I needed to start it again, but as soon as I needed it to start hot for me, nothing. How long did they have it for? I did my stand pipes and dummy plugs myself and I doubt they actually tore it down to make that statement. They probably put their scanner on it and cranked it and saw enough pressure to start it cold and said get it out of here. Let it get warmed up and then shut her down (when you don't need to get anywhere, just in case), and wait 10-15 minutes and try to start it again. If it won't start then they're wrong. If not, then yes, isolated incident. But I have my doubts. Stand pipes and dummy plugs are more common on the 05-07 6.0's.

I have been driving it for a week now and it has been starting perfectly but i think im still going to buy the stand pipe and dummy plug kit from bulletproof. might as well do it before it goes. there were 3 codes that came up refering to the ICP sensor so im going to replace that as well... apparently it also can cause starting issues
