multi inj failure

Rate this topic


Recommended Posts

Anyone seen something like this? p0266, p0272, p0278, p0304, p2291, cylinders 2,4,and 6 codes. Truck only skipped on number 4. Ran power balance to verify. Checked relative compression good. short term trims good except #4 at 17%. Checked all inj resistance and 200K on all. Replaced number 4 and after start up and everything bled out it skipped on #2.

 

Should I be thinking about putting an injector in #2 and #6 holes also? Customer is down and about 1000 miles from home. I kinda would like to fix it and get 'em on the road in a timely fashion.

Hope this doesn't sound terrible, but did you check the engine oil and make sure its not over-filled? Had same issues and was crank slapping away deep in the engine oil. Would of never believed it. Second did you verify fuel pressure?

Yes and yes, oil is right on the money and was just changed. Same for fuel pressure and filters are also new.

 

Truck is a '08 F-350 King Ranch dually, with 25k on the clock. Guy said he was driving along and it stumble a few times then he hit one of our mountains and that was it, truck wouldn't make it over the hill. Called roadside and they towed it to us. I drove it in clearly running on 7 cyliders. Ended up putting an injector in it and it still runs on 7, just 7 different cyliders now.

had one about 3 weeks ago. engineer got involved. found water in fuel caused high pressure fuel pump to come apart and sent metal to injectors. had to replace pump and all 8 injectors. went on test drive only to find pressure regulator on the new pump was bad. replaced pump again and retest. customer said truck is ok. good times. hope this helps


I find this quote from the "boards" rather disturbing, because I found some water in the fuel tank of this truck I am currently working on. I am not sure if water made it to the engine or not.

How much water was found? Yes ur right that quote is disturbing. Gota tell you, i had allot of 6.4 litre equipt trucks in with water in fuel message blazing in your face and the customer states in a joking manner "its been on for months" and never had a hp pump fail for water. i thought they were more durable than that. has to be more than that. did you get the hotline involved?

had one similar to this customer put gas in instead of diesel died while driving. scattered hp fuel pump replaced pump and all injectors and fuel logs cleaned tank and lines left for a couple of days and then died again hp pump failed. replaced pump again and started and missed cut open fuel filters and found metal in filters. there is metal contamination on return side of fuel system bouncing around causing a miss fire

I have the head off one right now (new head finally came in this past week while I was at school). Customer states that he got water and "black floaties" out of the separator. Drained about 30some litres out of the crankcase. With fresh oil, I had a steady miss on cylinder #1 and it didn't run long before it dropped #2.

 

I'm going to download my camera right away... might be something of interest.

It had code p2269 so I drained the seperator and it had water in it but nothing that I would consider to cause some sort of catostrophic failure. I ran the truck while doing tests and took more samples and the water content was neglagible in my opinion. I am going to run it by the hotline tomorrow and get an idea on which way to go. My main concern besides fixing the truck correctly is I want it out my bay and back to the customer in a timely fashion. I have heard some bad stories of trucks being held up for weeks waiting for fse's and ect.

The customer stopped and got fuel and then the water in fuel light came on. The separator was drained and the vehicle went 150 miles. Then it started running rough. The vehicle was towed to the dealer and cylinder #4 was dead. There was very little water found in the fuel. The #4 injector was replaced and now #2 is misfiring.

 

 

4/14/2008 9:59:00 AM - Hotline recommended:

 

Brad, lift the rear of the vehicle and remove the #2 injector tube. Strain the fuel from the fuel rail through a clean paper towel. If any metal is found then replace the HPP, 8 injectors, fuel rails, fuel cooler, fuel filter, drop and clean the fuel tank, flush the base fuel lines and flush the returns lines in the cylinder heads. Fill the vehicle with clean ULSD and retest for normal operation.

And the very last statement by the fellow was, it Ain't covered by Ford warranty. /forums/images/%%GRAEMLIN_URL%%/whattodo.gif

 

Now I just read a post about the tsb for water entry into the rear tanks on these doing the same thing. /forums/images/%%GRAEMLIN_URL%%/scratchhead.gif

 

We have the worst fuel sources in the country and I am thinking that if all our customers have to get there truck repair bills paid by the selling fuel station, then there are going to be seeing some stores going belly up quick. We are going to have trucks stacked up out back like cord wood, you know what I mean.

 

I called the fellow whom I quoted, he is at a dealer in GA. He said they had the truck a month before sorting it out and Ford paid the bill. I don't know but I see this turning into a bad situation for everyone that has to deal with these fragile powerplants. I mean this is like a blood clot bringing down that wrestler "Big Show". /forums/images/%%GRAEMLIN_URL%%/banghead.gif

Well I pulled the left valve cover again and removed the first injector tube, stuffed a coffee filter under the rail and jacked the back of the truck up, way up. The fuel was clean and had plenty of lubricity. So I replaced the injectors that I had codes for, changed the fuel filters and put some 911 in the tanks. Got the truck running after I bled the high pressure fuel system (which makes things go very smoothly BTW) and performed high pressure leak test.

 

I drove the truck home and put 200 miles on it, draining the water separator at every 100 miles and it ran flawlessly with a tiny bubble of water in the container I used.

 

Gave the truck to the customer and he drove home to Indiana, about 1000 miles away from us, and did the same and called me to report the truck is running like brand new without any troubles, at least for the moment.
