2005 F 250 Super Duty Question...Long Ramble
Greeting All! I have a '05 F 250 Diesel that has always been serviced, checked, and kept up, and currently runs and sounds great. In April '15, we were coming home from Georgia to East Texas, and in T...

The no start problems are frequently caused by the Fuel Injection Control Module, or FICM. I've had two of them on my truck. I got home from a cross country trip once and the next morning the truck wouldn't start. I was glad that it waited until I got home to break.
HANK85713 brought up a good point. My truck would run really rough sporadically and got to where it would stall. It turned out to be a broken fuel pressure modulator spring. Ford had a recall on them because the spring would either get weak or break. They're pretty easy to change and cost around 30 bucks. The "Blue Spring" is the replacement.
The key to keeping these engines running well is regular servicing. They're very sensitive to oil and fuel contamination.
The Fuel Injectors are actuated by high pressure engine oil. It's very important to keep clean oil in the system or you'll have sticking injectors. All diesels require clean fuel. Make sure you change the fuel filters at the proper intervals and get your fuel from a reputable source. I like to get mine from truck stops. They have a high turnover on their fuel, so it's less likely to have moisture and sediment.
I had the hypermax ECON tuner on my truck. Some folks think that this is what caused the issues with the head gasket. I got 24 mpg on the highway during one trip and 14 mpg while towing my 7 ton FW. It had great performance. Unfortunately it improves performance by advancing the fuel injection timing. It creates more cylinder pressure. If you're going to use something like this you should invest in ARP head studs.
