2004 6.0 no tuner that I know of. 5" MBRP Exhaust turbo back, AEM brute force intake. It has been cold here but, I have recently picked up a hard start. Cranking rpm's seem normal, just takes longer to start, glow plugs seem to cycle normally. When it fires off runs rough and heavy, heavy black smoke not just a little. It now has a shudder or miss in OD goes away when in tow mode. I have a scan gauge II but no codes show. Any ideas??

 

Couple of thing I would start with. Check batteries. Load test each battery. Check fuel pressure. Anything under 45lbs is a no go. If you havent updated your fuel regulator spring, be a good idea to do it. I would also change fuel filters. Oem. Might also be a good idea to get a scangauge 2 to be able to read live data.

 

Some things you can try in addition to what was previously suggested is, compare MAP, BARO and EBP at KOEO, they should all read within .5 PSI of one another.
Next would be to check and clean the MAP hose and hose nipple at the intake manifold, the MAP sensor is located just above the evaporator housing on the passenger side and is connected to the passenger side of the intake manifold via a rubber hose, make sure the hose is clear and in good condition and make sure the brass nipple on the intake is clear.

Next check the EBP sensor tube and make sure it is clear, the EBP sensor is mounted to the thermostat housing and is connected to the drivers side exhaust manifold via a steel tube, remove the sensor and run a piece of stiff weed whacker line through the tube and into the exhaust manifold, a pipe cleaner could be used as well, just be sure the engine is cool before you do this.

Next remove and clean the EGR valve with carb cleaner, just be careful not to get the carb cleaner in the top part of the valve where the electronics reside.

Next you can clean the MAF with MAF cleaner, the MAF is located in the air inlet tube just after the air cleaner.


Also the scan gauge II is not a good code reader, I would drop in to your local autozone and have them read the codes for you as you can have pending codes that will not set a check engine light

 

It will be a few days just got too many things to do. I will check and load test both batts separately. Probably not the problem -- new 4 months ago cranks good also, but still could be. I would agree scan gauge 2 as a bad code reader. I have only had pu 4 mos. and 12,000 miles and with all its got going on there has to be some codes -- scan gauge picks up nothing, probably was a better choice for a scanner gauge package lol. I clean the MAF when changing the oil with correct spray. Nearest autozone is 60 miles away - don't live in a populated area. Will check n clean all else mentioned. At this point I don't think a 6.0 will ever be as reliable as my old 7.3 idi. With high performance comes high maintence. Thanks for the help will post back later.

 

Oh yes it will, you just need to get on top of some of the maintenance items that may have been neglected in the past and you are already on the right path monitoring things with the scan gauge.

 

FICM main and logic power are very sensitive to condition and functions of batteries and alternator. Check all battery cables and grounds. FICM functioning improperly may be the cause of some of your symptoms. The other good advice is the MAP, baro and the cleaning of the tube! not just the sensor. I also wonder about glow plugs, glow plug harnesses, control module. This 6.0 is a lot more complicated than your IDI was and with that comes power amd maintenance. Let us know how yo make out with this stuff, we can help with ideas and hopefully point you in the right direction.

 

Fresh oil change w/Delo full synthetic 5w-40 same as before using all motorcraft filters. checked/ cleaned EBP, MAP, MAF, cleaned battery terminals & load tested. Started better but still HEAVY black smoke but cleared up quicker. Runs the same - engine miss intermittent. Borrowed a Edge CTS insight have these 5 codes P0275, P0281, P0603, P1000, P2290. EBP also is not reading. At 60mph 1750 rpm, BAT 14.3v, MAF 9603, ICP volt 1.3, ICP#1275, FICM 48.5v, MAP 22. Cleared codes drove more only P0275, P1000, & P2290 came back. Probably gonna do a ICP. Do you think a injector replacement is in order the miss is intermittent. Usually only occurring in OD. Thanks

 

Check your fuel pressure and post you ICP and IPR at idle. I think you need to pull the IPR valve and check for trash. If the ICP is under the turbo it's an 03 motor and you probably won't get EBP.

 

Looks like injector 5 & 7 ( which are right next to one another ) are having issues. Agreed on checking the fuel pressure as NPCC suggested, needs to be above 45 PSI at all times including WOT. But my guess is 5 & 7 will need to be replaced and may have been damaged with low fuel pressure. If you do replace them make sure you use OEM remanned injectors. It would also be a good idea to do a bubble test, remove the upper fuel filter and with the filter and cap removed crank the engine over as shown in this video and watch for bubbles,

 

ICP voltage at idle .9, ICP 580#, IPR 24%. Probably will clean ICP today or tomorrow sometime. I think it just needs $ spent on it like a trophy wife!No real rhyme or reason just wants attention

 

Changed out ICP, cleared codes and drove. Now am showing only the P0275, P01000, P0766 & P02073. Feeling better. Is the P01000 code normal? The transmission codes can be addressed by trans shop. Transmission was rebuilt when I purchased truck. Anyone want to guess if P0275 will ever clear up? Still have a starting problem. It mostly appears to be calling for too much fuel -- smokes black like a freight train. EBP also never reads - normal? Thinking I need to compare IAT1 to IAT2 along with EOT & water temp.?

 

Gauge readings, first it is hard to get readings @ 2500rpm. The motor takes off at 2200 ish and heads straight to 3500+, IPR will go to 85% & ICP 1587 this is like wanting to go WOT. What is causing this?
Readings KOEO/1100rpm/2500rpm MAP=13.014.0/17.0, BARO=13.1/13.1/13.1, EBP never reads is this normal? manufacture date of pu is 10/03. ICP=0/700/1500, ICPV=.2/1.0/3.0, IPR=14%/27/56, IPR=14.8/28.5/50.6, FICM= 48.5/48.5/48.5, VLT=11.8/14.0/14.0, Engine temp 186. On cold soak EOT=38.3, TFT=36, FIA=37, FWT=37, IAT2=37. Sometimes on start up gauges won't read, it's like obd port is powered but scangauge or edge cts is frozen, obd ports or computer problem? No bubbles on bubble test. I have to get something put together to test fuel pressure unless 1 of these gauges will pick it up, but I don't think they can. Anyone see anything ?? Thanks

 

Just realized my secondary fuel filter stand pipe is broken/parts missing. What problems would this cause?
