Ok, so I've got a 2006 F250 SuperDuty w/ a 6.0L. Bought this truck in Sept '14. Since then, I've replaced injectors (or had them rebuilt) no less than 5 times. Just did it again in early December. I don't drive this truck daily. I had to swap out the motor last February, and had the new one fire-ringed, bullet-proofed, basically anything & everything the shop could do to upgrade the motor. I still have to keep replacing injectors. After replacing them in Dec, I drove it maybe 100 miles, then took it on a 320 mile one-way trip last weekend. Truck ran great, probably better than it ever had since I've had it. We live in MD, and were just got about 3ft of snow in the past 2 days. Took it about 30mi Friday night & back Saturday afternoon from pushing snow (w/ my four-wheeler, not the truck), and back again this morning. Now it's running like it's missing again (like it did last 2 times I replaced injectors). Getting real tired of replacing them. Due to the engine swap & accident that led to it, there is very little that hasn't been replaced under the hood. I don't know where to even start trying to figure out why they keep failing, but I know I can't afford to keep replacing them. Any ideas what to look at / test?

 

anything under 45psi of fuel pressure will kill them. Check your fuel pressure and add the blue spring upgrade, it increases the pressure. What is the fuel control injection modules output voltage? Have you checked the fuel pump? Changed filters, both of them? Added any fuel anti-gel to the tank, its cold in MD.

 

I agree. I would suspect low FICM voltage or low fuel pressure.

 

Where are you located? I drive up 301 from King George, VA to Andrews AFB, MD Sunday-Thursday. I have troubleshooting capability and can help you out if you're on the way. PM for my phone #.

 

I have to ask, is this the SAME SHOP that has done these five times?
If so, then ask them why in the H E double hockey sticks they keep failing.
If they can't give you an answer, then fire them.........they have no business working on a 6.0, or any other diesel for that matter.

There is no reason they should have not checked the pressure the first time you had it in there. It's called being incompetent.

As the others mentioned, get a blue spring update and make sure the FICM is putting out proper voltage, as well as the rest of the charging system.

 

...and I am up closer to Baltimore...in Millersville. I have a ScanGauge I can hook up to your 06 to be able to tell you what your FIMC voltage is. Take just a few minutes.

 

Dude hasn't been back on FTE since he posted.

 

Ohhh...I didn't even LOOK at the danged DATE!!! And he has a grand total of TWO posts.
