I got my 2006 throwing codes for two injectors only in the mornings on a cold start. If i plug it in it does not do it. But i did notice that if you put it in park and rev it all the way up till it red lines that it will sputter a little and blow blue smoke. It does this after it is warmed up. Do i have bad injectors or do i have a stickion problem. Thanks

 

i'd guess stiction issue.when it's cold (20's)my 04 will idle fine but as soon as i get it to 1000rpm it'll miss until it's warmed up, and it'll blow blue smoke at wot also, which is more than likely a sticking injector. if it were me i'd change the 2 that are throwing codes. as soon as i find out which one i have sticking i'll change it, but it hasn't told me which one it is yet.

 

I was just wondering if low fuel pressure would cause the same problems. The reason i ask is my fuel pump is not as loud as it used to be. The filters were just changed about 1500 miles ago used ford filters this time. It acts like it is starving for fuel just like my old 97 powerstroke did. Hard to start and sputters at high throttle. I changed its pump and did the bb mod and never had any more problems. Just curious how long the 6oh fuel pumps last. My truck has never had one in 145000 replaced. Also my fuel mileage has dropped significatly. Thanks

 

I would sure suggest you check your FICM voltages and consider installing a fuel pressure gauge.

Are you using a 5W40 oil and when was your last flash update?

 

Well i checked my ficm last week. It showed about 49.5 volts with koer. Now the volt meter i used noah used it while building the ark. All my diagnostic tools are in kansas locked up in my service truck while i am in tennessee. I will go buy a new one to test it today plus will try to check fuel pressure also. To check it i just need to remove the plug on the sec fuel filter and install my gauge assembly there. Correct? None of this started till after my little brother put atf fluid instead two stroke late last year in my diesel. He is not the brightest bulb in the world. Thanks again

 

Hopefully your "repeat" tests on the FICM voltage shows to be good.

Yes, the easist thing is to put the fuel gauge on the secondary fuel filter test port, but you will need an adapter ( M12x1.5 to 1/8" NPT fitting). I like the ITP fuel pressure gauge hose - it has the fitting that you need and it gets the point to attach a gauge out in the open. It has a schraeder valve on the end to help make sure it is "liquid full". The best way to test fuel pressure is at WOT, but if you have fuel gelling, etc, even fuel pressure at a high idle can give you some good information.

 

I am just curious but if i need injectors is there any way to clean the spools that are sticking. Or could you get in the injector and put a spring like in the 7.3 to help out. If i need them i will take one and break it down to see. Another question where is the best place to buy the fuel pump and injectors from?

 

I have read about a few places looking into "refurbishing" the spool valve. I never saw anyone that was successful at it.

There are a number of dealerships that are willing to give discounts on parts. Tousley parts advertises cost +10%. They beat the prices at my local dealership (who seems to have lately begun to "push the envelope" on their repair jobs being limited to ONLY the work that is needed).

Also - Ed the parts guy has good prices!

Several choices for aftermarket injectors would be Elite Diesel, River City Diesel, or Full Force Diesel. I have no opinion on these.

 

try this place did me right

you didnt say you had starting issues in your first post so disregard mine.bismic, where do you check ficm voltage at?.

 

How to check your FICM for proper voltage output.
(Perform this check when the engine is completely cold.)
1. Remove the two bolts that hold the coolant reservoir to the cowl and push the reservoir out of the way forward and to your right. You do not need to disconnect any of the hoses.
2. On top of the FICM is a small cover held on by two #20 Torx screws; remove these two screws and pry the cover off.
3. On 2003 and early 2004 trucks, you will see 7 screw heads under the cover. On 2004.25 and later trucks you will see 4 screws.

PROCEDURE for 4 SCREW FICM
4a. Take a multi-meter set on DC volts and connect the ground lead to battery negative, and with the key ON measure the voltage at the screw on your right—closest to the driver’s side fender. Do not let the probe short against the case! The voltage should be right at 48 volts. Anything between 47 and 49 is good.
5a. Have an assistant cycle the key and measure the voltage during the initial key-on buzz test. Voltage should not drop below 46 volts.
6a. Next measure the voltage while cranking the engine. If voltage stays at or above 45-46 volts, the FICM is fine. Abnormally low battery voltage can give a false low FICM voltage reading, so make sure your batteries are good.

The procedure is the same for FICM’s with 7 screws, except that you will be checking voltage at a different screw, as shown in this picture.

https://www.ford-trucks.com/forums/a...ictureid=19315

PROCEDURE for 7 SCREW FICM
4b. Repeat step 4 above (multi meter step) but put the positive lead on the left-most screw in the row of 4 screws.
Do not let the probe short against the case!
5b. Same as 5a above
6b. Same as 6a above
If the voltage is above 46 volts in all the tests, your FICM is in excellent condition.
If it is between 36 and 45 volts its OK, but not great. If it is between 25 and 35 volts, you have serious FICM problems.

 

thank you!

 

Alright i decided to go out in the cold today. Went to the shop and pulled my truck in. I was going to check fuel pressure but had every fitting except the one i needed. So i loosened the secondary fuel cap and turned the key on. The fuel was not spraying out like i thought it should so i did the bb mod. I also cleaned the egr valve. It was not that bad but i cleaned it anyway. I disconnected the batteries and cleared the computers. Then i cranked it up and did vgt relearn. Got in a took off back home. My fuel mileage before all this was 13.8 by the lie o meter. On my way home i decided to take the long way home (about 20 miles) well the computer showed 17.6 when i arrived home. I made sure i did not look at it until i got there. But anyways the truck seemed to run a whole lot better. It didnt sputter like before. I know i probably just put a band aid on a heart attack but i will try to get pump this week and put it on. One question is do i go back with stock or upgrade to something better.

 

what is vgt relearn and bb mod just never heard those terms before thanks
