Suprise Suprise, less than a week after purchasing my first vehicle, which happens to be a 6.0, knowing ahead of time about the headache they can cause, I'm here asking for help!
I picked up a 2006 F-250 with 74K last Tuesday. Everything went perfectly during test drive, noticed a few things here and there cosmetically that would need help, and planned on doing the normal mods as I got the time and money....But FIRST I have to fix the problems!! This is now my daily driver and essential for my job so need to get something figured out soon!
Here's the story: Less than an hour after buying it I had new tires put on to replace the bologna skins it had. When it was done, the pickup wouldn't start! Talked to the shop foreman and he said it was hard to start after the change. Figured it was bad fuel, plugged filters. I tried about anything I could think of to get it started. Hoping the gauge was bad I added fuel, tiny sqirt of starting fluid verified it wanted to run but lacking fuel. Checked fuses and pushed fuel pump reset and it fired up. It had been roughly an hour of not starting before it went. No problems the rest of the day.
After putting about 600 miles on it after purchase, during my trip to town to pick up oil, filters (including fuel), and coolant flush materials, after dropping about $300 in parts and accessories I stopped for lunch and then again, crank but no start! This time I was in contact with a Ford Diesel Tech, I tried everything I had the first time, replaced my upper fuel filter since I had it and my tools with me. Also cracked the fuel input line and verified fuel was flowing that far. The tech told me to check the output from the filter housing. Cracked them loose, verified fuel was flowing out when pump was on, put them back together then PRESTO! Fired right up. I had tinkered with it for almost an hour again. That's when the researching began, I have read many threads on this, but it seems that the final solution never gets posted...or I'm just missing them.
Today after a long night of work I decided to run into town to treat myself to some breakfast. Let the ponies run on the way to town, went to restaurant to eat, then stopped by hardware store, dropped about $80 on a dremmel and other supplies for the ZooDad mod. Got back to the pickup and for a third time it wouldn't start. Now with my research I was starting to think the STC's were leaking, but the temp needle was barely above the C mark. Was looking up a couple threads on my phone to verify some of the trouble shooting procedures I had read, also I was going to crack the lines like I had last time. Given the last two experiences I was expecting an hour of downtime. Decided to try it one last time before tearing into it and it started right up. It's like every time I go somewhere to eat and/or spend money to help it out it doesn't start! On the way back to work I tried to duplicate the symptom before bed. Again I let the ponies run on the way back, parked it, turned it off, and left it set for an hour (all problems seem to be after it sits for 45 min-an hour after driving) During this time I reattaced the tailgate that decided to jump off within the last mile of my trip!
and did the ZooDad mod. Anyhow, the time, engine temp and everything else seemed to be right where the problem exists, turned it over and it fired right up!
I want to get this figured out before I continue dropping money into it for the mods so I have a couple questions to help my troubleshooting process:
Obviously, Any Ideas??
Any tests I can do to test potential causes? I have pretty much a full set of tools from auto tech school (light duty) A multimeter, and a Harrison R&D scanner. Can I use the multimeter to test the FICM? If so, where do I hook up? How about the ICP and other sensors?
Any easyish way of testing/inspecting the STC? I'm not noticing any noticable oil leaks.
This morning was the coldest it ever was when I started it but still not that cold, but it ran kind of rough until about 93 degrees (Had Harrison R&D hooked up) Possible sign or simple stiction?
I have never worked on Diesel's before, but shouldn't there have been fuel with at least some pressure in the lines when I cracked them loose? Thinking that might be a sign of a leaky fuel system.
Thanks for the help! I am officially addicted to this site now!!
