Need help 2006 6.0 No start

2225 Views 43 Replies 7 Participants Last post by  bismic
I’ve got a 2006 6.0. 191,000 miles was bulletproofed, studded, new heads and a few other things done by previous owner at 162,000. I have receipts. Truck sounds like it surges going down interstate and has started dying on me. Sometimes it will start right back but when it won’t ipr duty cycle goes to 84%. Sometimes I will have to let it cool down, sometimes it will start back after just a couple minutes. Am I dealing with a faulty IPR? TIA

I also like DieselFiltersOnLine for filters, and sometimes you can get Ford engine parts (like the HFCM, glow plugs, etc). They don;t seem to have the IPR for a 6.0L though. The best thing about DieselFiltersOnLine.com is that you can order all your OEM filters from them and add on another part or two and get free shipping on $250+.

I got my ipr and pigtail ordered just now from riffraff. Gotta get ipr socket ordered and I’ll be set. I appreciate your help. I’ll report back this weekend and let you know if the ipr or harness was the problem.

How do I close the thread? I’m a newb here.
I just meant to post a conclusion (I call it closure). Nothing special. Sorry to confuse!
Oh I gotcha. That’s my bad. Will do! Thanks once again.

I know you've already ordered, Also bismic is awesome and has been a huge help to me through the years... I would say spend the time diagnosing with the 6.0's though otherwise you can end up throwing a ton of unnecessary $$$ at them... just my two cents .. 200$ worth of diagnosis beats 400$ worth of part swap in my book..

I agree with you 100%. I threw a bunch of money in parts on my 7.3 and got me no where. I’m not smart enough to diagnose and hate to have it at a shop because I rely on the truck everyday for feeding my cattle. Just hoping it’s ipr based off how it’s acting.
The socket from some of the auto parts stores is less than $10 -- autozone where I picked this one up
OEM Tools #25280

IPR connector gets a lot of heat from the exhaust where it is located , the wires get cooked -- there is a heat shield, but sometimes is left off cause it is a pain to get to the rear bolt

So I installed the performance canned sct tune while I’m waiting for my innovative tunes. Once I get to about 3/4 throttle the truck really takes off and my ipr duty cycle goes to 84% and icp 3000 psi. Should my ipr duty cycle be going that high and holding there?
Sorry, I don't think much of the canned tunes (forum feedback in the early days), and I have avoided them.
I’m fixing to get my custom tunes moved to device and installed and see if it does the same thing. Still haven’t put new ipr in should be here tomorrow but have read that ipr duty cycle shouldn’t go above 65% or so at wot and this one hits 84% at 3/4 throttle. So you think that might be because of the canned tune?
I don't have a problem with a higher IPR duty cycle at WOT as long as you have enough pressure and power.

I think that the tune MIGHT be causing issues - I can't say for sure though.

It’s got all the power in the world and holds 3000psi. It’s weird just easing into the throttle once you hit 3/4 throttle it takes off like a rocket just seemed kind of weird but that may be normal. I’ll get the custom tune installed and see what the duty cycle looks like. But that 84% doesn’t sound high to you? Once it hits 84% it won’t go any higher even with more throttle but icp holds
84% is max, so you won't get any more when you hit that. I wouldn't want to see 84%, but again - if you are getting all the power you need, then it isn't an issue at the moment. I was primarily stating that I don't agree that it should never be over 65%.

It is certainly possible that you could have a small leak that is causing the high IPR % duty cycle.

Ok, I’ll get this custom tune loaded and see what happens. I’m not a fan of canned tuning myself. I know prior to installing this canned tune the truck didn’t buck and take off like it is now. I’ll report back shortly on the duty cycle. Once again I appreciate your help.

Tunes in general mess with the engine parameters, making the readings mostly useless -- return to stock if you want to see where the system is having problems

3000 psi, OK -- but what is the ICP voltage ? -- 3.8 volts I would hope
else the tune is messing with the pressure numbers

I’m getting these pids off my sctx4. Can I see icp voltage with the sctx4? Was thinking my only options were icp pressure and icp duty cycle which I’ve been told is actually ipr duty cycle.
Need to get ForScan -- here is the info

Gonna own a diesel, you need to be able to get codes and monitor the system when there is a problem

These should be mandatory for any 6.0
Fuel pressure gauge -- M12x1.5 thread adapter
Base oil pressure gauge -- test port on front of oil cooler housing 9/16x18 imperial o-ring fitting -- Parker snap fitting
Cooling system pressure -- tee in the small vent hose near the coolant bottle

I suggest downloading ForScan and using the OBDLink MX+ or the BAFX adapter for troubleshooting
Torque Pro would be good for everyday use with an old phone or tablet
Scan Gauge is small and simple -- can be mounted in front of the instrument cluster
There are other monitors, but the price goes higher (SCT, Edge)

ForScan is a simple download for PC, you can get it in just a few minutes -- the "lite" version is available on the app stores for your device.
There is a "demo" in the app options, so you can use the app without being connected, to get familiar with the screens
The BAFX adapter is the least expensive and a reliable adapter -- the MX+ is smaller, faster and more features, especially if you also have other newer vehicles

You do not need the license for troubleshooting - only for advanced programming
The PC version is the most powerful and does the injector "click test" among other tests

Got the performance innovative tune installed, truck was smooth all the way through throttle and ipr duty cycle never got over 74% hard throttle. Going back to my original question, so I drove the truck all day yesterday without it dying or having hard starts and last night it died on me. Got it started after it cooled down. Drove it all day today, over 100 miles and never had an issue. If my problem was because of a hpo leak, wouldn’t my problem be showing itself consistently when I got up to temp? The way my problem is sporadic makes me think even more it’s the ipr valve or pigtail. Am I wrong in my thinking?
