Well I'm looking at spending some good hard earned money it seams lol.
Truck has developed a random hard start issue after it is warm. Just keeps cranking like crazy.
WARNING LONG DESCRIPTION
Here are the stats and history of the truck.
2005 Ford F250 CCSB 4x4 lariat.
Engine is all stock except for AFE intake that was on the truck when I bought it in 07 when it had only 19000 miles on it. Before I bought the truck I did a carfax and oasis report and both had nothing on them except a door rattle fix on the oasis. I have always changed the oil every 5 to 5500 miles and changed the fuel filters after every other oil change. Did the big service with a coolant flush at around 55k to 60k miles at Spradley Barr Ford in Fort Collins CO all fluids were changed and truck was gone though and everything was top notch.
In 09 noticed a little oil residue at the front of the engine so when I took it to Ford for the oil change I had them check it out they said nothing to worry about.
Since then no problems to speak of until last year @ 74000 miles or so. Early summer of 2011 I was in LA and truck would start just fine then as soon as you would try to go it would start missing and falling on its face at 2000 rpm. Had to let it idle for 10 minutes after reaching normal operating temperature and then there wasn’t a problem. I was able to get back to the bay area (Redwood city/San Francisco area) with no problems. Then put it on the scanner and found that FICM went bad. Got a remaned one from Swamps diesel and gave them my old one. After that it ran awesome, nice and strong.
Everything was fine, no issues till September 2011. Went to visit my mom in Truckee CA near Lake Tahoe and decided to take the boat too (4500lbs). So the day I left to head up with the boat it was 95 degrees outside at sea level. Everything was fine heading up the summit (went from sea level to 8800 feet) cruising right along 70mph not using AC just windows down while climbing the summit. Then near the summit we hit road work and had to slow down to a crawl then 5 minutes later I hear a pshhh sound but no steam from the hood. I get off and open up the hood and it puked but not very much at all. So I clean it up and let truck rest and then continued on up. I ran it hard to see if it would do it again and still never has. Coolant has been at the correct level always.
Once again no issues until February 2012. Drove down to LA everything was fine then on the way home after the weekend was hauling a$$
up the grape vine boost not going over 23 psi until close to the top where it reached about 27psi but then I heard a sound like it was missing or like steam blowing off in spurts. I pull over and pop the hood and nothing. No degas bottle puking, no fluid on the ground, no steam from anywhere. I was at a loss to what happened. Got on it again and everything is fine all the way home 455 miles. Mind you I have never seen any different colored smoke out of the tail pipe other than when the FICM failed.
Current no start while engine is warm issue first happened in March. Put it on the scanner no codes and at that time it was ready for an oil change and new fuel filters. So I went ahead and changed everything. Well started every time since until 2 weeks ago one night at the bank. Turned over like crazy but didn't catch. Waited 10 to 15 minutes fired right up. This issue seems to be very internment.
Now I am at a crossroads it is time for all the fluids except oil to be changed. Like coolant, diffs, transfer case, transmission etc...
I am trying to figure out how far I want to go with the fixes. And here in California I can't get rid of egr or change the exhaust much. When I had the inspection they checked everything under the hood and under the truck and plugged into the monitor and not really wanting to change parts back and forth every other year.
Running at 70mph for 45 min on the flat.
EOT: 178 F
ECT: 184 F
FICM: 48 to 47.9
IAT: 123 F
IAT2: 154 F
INJ Press: 15
MAP psi: 14.9
EBP psi: 14.9
Parts I want/need to get:
1. Edge insight CTS with EGT probe
2. BPD oil cooler
3. Blue spring update.
4. BPD EGR cooler
5. New rear diff cover w/ cooling fins. What’s the best? I tow often.
6. Possibly ARP head studs with OEM gaskets but don't think mine went yet.
7. Coolant filter. Dono what's best?
8. Thinking of FICM tuning. Not sure if its worth it and what the long term effects are.
9. SCT scanner. What’s the best? Not looking for tons of power but some more and better MPGs would be nice.
10. Maybe exhaust, 4" but what is the best way to go when having to keep the Kitty??
11. If money allows me I want to get SCT or SCT x3 tunner
Things needed to be done.
1. Pull the egr and check/replace
2. Pull Turbo and probably clean it.
3. Perform a coolant flush and change over to ELC or whatever is best. Currently running Ford gold.
4. Check /replace HPOP screen
5. Check / replace ICP sensor
6. Don't know if the STC fitting was replaced but no indication that is was so assuming that it should be done.
7. Check/ replace Stand Pipes & Dummy Plugs. What’s a good brand or company to get these from?
Sorry for the long post but might as get it all in one. Let me know if I am missing anything and all input is welcome on where and what else to get or need to do. I plan on doing the work myself as I have access to a shop with a lift and plenty of tools as well as mechanics however they have never done anything like this on a 6.0L. Would love to go to left Coast diesel and talk and or watch them do this procedure. I have soured the forum and printed out a lot of how tos and manuals to fill my 4” binder but knowing more never hurts. Thanks in advance and I will update as things change.
