Hot start, normal crank, low idle

Hey guys

So I just started noticing this recently, if I run in a store quick and shut the truck off and come right back out to start it. Itll start but ill be at about 500 RPM's, throttle is non responsive, and engine sounds normal just no exhaust sound. The first few times it only lasted a few seconds now close to a minute. I will hear the turbo spool up and exhaust will kick in then the truck run great.

Truck has 88,xxx miles
Deltas are normal
FICM is at 47.5 key on engine off
Recently changed fuel filters
Oil changed about 2k miles ago

Any ideas?

So I am pretty sure this is coming from a HPO leak. Problem as been getting progressively worse to the point im afraid to shut the truck off if id be needing it again within an hour. Today i ordered updated stand pipes, d plugs, updated STC fitting, and turbo mounting kit from Tousley for $150. I really hope this solves my hot start problems. Anyone have any tips, tricks, or things to look for while doing this process.

Thanks

Sound like your on the right track. You dont have a monitor? A 3/8 air rachet or a small cordless impact will be worth its weight in gold.

I hope so it has really become a PITA! Yes i do have a monitor ICP is usually at 500psi while cranking, anything else i should be monitoring? I don't think my edge CS can monitor IPR. I have the air ratchet just need to get a new fitting before i start

No, you can't monitor ipr, thats the only thing I dont like about my cts. I monitor, ficm, ect, eot, icp, batt, boost, vgt, and trans temp, or trans gear.

I do monitor all of the above they all seem to be in order (for the time being) with the exception of trans i have a manual so no worries there.

Hey everyone! So i know it has been a little while since i have updated this thread but here it goes. Suffered till I got home from school with hot start problems but started to tear into the truck little by little over the last few days. I hope to have it all finished by tomorrow. I am installing updated Dplugs, Stand pipes, and STC fitting. Between the weather, work, and the holidays I have only been able to do alittle bit at a time. Being that this is my first major mechanical adventure on my truck all alone I have been taking it VERY SLOW in order to not break anything, and keep myself organized to make reassembly easier. I may try to do a write when all is said and done for any other diesel noobs (was me not so long ago) but ill get to that. For now I just wanted to share a picture(s) (more to come) with all of you. I know many of you have put blood, sweat and tears into your trucks well i have joined the club.
