Hard start all temps

[jhelmsing]

I have an 06 6.0L that has recently started giving me fits. The truck starts, but only after cranking for 15 + seconds which it did not do until a week ago. I initially thought it may be the FICM again, so I checked it and it never dropped below 47 volts either in start or cranking. I then checked the glow plugs at the harness and they were all consistant at about 0.5 ohms. I have no codes when I hook up the scan tool. I then tested the batteries and they were weak, so I replaced them. This helped a little, but the issue still exists. I then went back and started checking again when I noticed the fuel pressure regulator leaking. I ordered the kit for it and fixed the leak (as well as installed the new blue spring). The problem again got a little better, but is still not right. I've basically moved from near no start to 15 seconds of cranking to start either hot or cold. I'm considering replacing the o-rings on the dummy plugs next as a shot in the dark (don't have the means to read the sensors), but want to get some additional input. I don't have alot of time due to my next haul being in about a week and no time off in between (have to work on it in the evenings). Any clues here?

Go to Auto Zone and pick up a ScanGaugeII they cost $160.00 it will read everything the pcm sees.
Set it up to read the:
ICP injector control pressure
IPR injector pressure regulator

A healthy hpo system will be 585+ on ICP and in the 20-30 on the IPR during crank.
Since the truck is startable at idle you should be ICP 585 ish at idle and 21ish IPR Ford says anything above 30 IPR is hpo leak that is in need of repair.

I have all the PID,s for the scangauge for the 6.0 if you need them.
Btw the scangauge can be left plugged in and you can moniter all the engine values oil temp/coolant temp/ficm voltage/egr/turbo boost/ on and on again it will monitor everything the trucks computer does. Best scan tool for the money by a long shot..........

Please send me the codes for the Scangauge II if you can. I may have to break down and buy one when I go to return some cores to AutoZone tomorrow. It seems like a pretty decent tool for the price, not what I wanted to spend my money on right now, but worth getting the truck fixed.

Here you go, to be honest I was a bit unsure when I bought mine but once I saw what it can do I was happy I did. Was honestly without a doubt the best money I have ever spent on the truck!!

Mhatlen, did you get those parameters from Ficmrepair.com's website? I didnt do a sideXside comparison but if you didn't, maybe his numbers are good vs. the numbers you have that arent working???

Yea Ed gave them to me himself, he said if you would have had a scangauge he wouldn't have been able to joust you for $400.00 bucks.

WTH.........
