6.0 will not start when hot...sometimes

2005 6.0 will not start when hot.. sometimes. If it cools down for 1 hr or so it's ok. 2 different shops said it was the oil sensors in the heads, 2 in each, $1000 to if I am lucky, every time I took it to a shop it would run fine, no problems 6 times at one shop.I have a Cam OBD2 when I test it I get "turbo/super charger under boost" PO 299 generic. then the yellow light comes on under emission status. I cleaned the batteries, new this yr, and changed the fuel filters, so far so good. but what is PO 299???
One more thing when it did start for a few min. there was no throttle response, the engine would only idyll. I do not have any tools to test things with, except a volt-amp gauge. Thanks for any help.

Try unplugging the ICP sensor and see if it will start.

Either way, you more than likely have a HPO leak. Could be the HPOP, STC fitting, standpipes, dummy plugs, IPR valve, any of the mentioned or a combination of them.

If you have the time, general knowledge, and ability to turn wrenches you can tackle it on your own instead of having a shop rape your wallet to do it.

Thanks Rattlesnake18 I tried that one time burned the hell out of my arm. Like I said I cleaned the batteries, had blue stuff on them, and I changed fuel filters, 12000 miles. So far no problems. Still looking to what PO 299 generic code means?

google it. 99.9% of the time it will come right up. Also try it in the search function up above. And if you look around somewhere on here is the 6.0 bible. Great info to download. I copied it off at work. And it has a section that has all the codes as well.

P0299 is the turbo over boost/under boost code.

Could be a dirty sensor or sticking veins in your turbo. I would check the EBP sensor first and clean the tube as well to start with concerning that code.

Ok where is the EBP? and how do I clean the tube? At least once a week on the freeway I put my foot in it, look at the turbo boost gauge watch it go to 20 or 24 for a min. and back off, is that enough to get the vanes in the turbo moving? truck runs really good at high rpm,

Here is a good thread to read.... 06 F250- EBP Cleaning

By the way, when putting the sensor back on, do not tighten it too tight or you will snap it off and have to buy a $130+ sensor, ask me how I know.
