2006 Ford F350 6.0 Wont start at all.
 

Hello Guys.

Year-2006 Ford F350

Motor-6.0 Powerstroke

Mods-5in exhaust

Recently changed- Fuel filters, icp sensor, crankshaft sensor, camshaft sensor.

Codes- Be back in one minute.






Well I been having an issue with my truck for the past 2 weeks Since I last put diesel. It hasnt started and shows no sign of starting. It can start for about 1 second with help from starting fluid but eventually die out. It had a misfire before Prior to not turning on. The truck has 123k, 5in exhaust catless, otherwise then that it is 100% stock. Since the day that I purchased the truck it was slower then all the other 6.0's and 7.3's my family and friends had.



Symptoms
Cranks but wont start

Scan tool Results
All 8 injectors were low
Crank Shaft sensor
CamShaft Sensor

Parts Replaced
CamShaft Sensor
CrankShaft Sensor
ICP sensor
Fuel Filters

I am a newb to Diesel, So some help would be greatly appreciated.

Thank you in Advance.

Check out the sticky at the top of the page and test your ficm... You got codes for your injectors so that could be it...

Check the wire harness to the ficm too it could have come unclipped...

First get your batteries load tested

Your crankshaft and camshaft positions sensors didn't need replacing. Those codes are typically thrown when trying to start a truck and it gets cranked over and over and doesn't start. Those two rarely go bad, and even more rare would be if they both went bad at the same time.

First things first, when you do crank it, are you getting any smoke out of the exhaust? If your answer is no, it's most likely the FICM. It could also be the high pressure oil pump, but the FICM is a common one.

Do what powerstroke814 said, read the sticky at the top of the page for instructions on how to test it.

Then report back here.

Welcome to DB!:c:

If it wouldn't start right after putting fuel in it where did you get your fuel ? Are you sure you got fuel and not water ? :humm:

update.

Scan tool's Keep reading the crankshaft and camshaft sensor. Go to crank it, doesnt start but throws black smoke out and acts like its want to start. We completely drained the Fuel and I went sunoco and put $50 bucks of clean diesel and still no start. HPOP is good as well so thats a relief. But there is still no start. And it keeps saying TBC faulty.

Load test your batteries. If one is bad replace both as the text will follow soon. Then test your FICM as the guys above stated. You can have your batteries load tested at about any local auto parts store for free. Also when you replaced your filters did you use Motorcraft filters? These trucks are really picking when it comes to the filters so you should only use Motorcraft. Most other brands dont fit right.

Tbc is trailer brake controller. I also get it once in a while.

The camshaft and crankshaft sensors are being falsely thrown from cranking a lot without starting.

If you're getting black smoke to me that tells me it's getting fuel, ie, the injectors are firing so the FICM is at least working enough to get it started.

How many miles were on this when you bought it? Just noticed you said it's been slower than your friends/families 7.3's and 6.0's... are those trucks all stock too? This thing should run circles around a stock 7.3. Sounds like it might be something a little more major here.

I would have a cylinder contribution test done.

Same thing happening with mine 06 Ford F-450 with 6.0L, wont start cranks but dont turn over ive tried everything and nothing seems to work. Got plenty of fuel pressure and oil pressure, no leaks on high pressure oil system either.
Changed camshaft and crankshaft sensor just to be safe, the FICM is good tested it already got 48V at it. but the truck wont start any one can help me out!

Does your truck have the butterfly valve under the intake elbow? Check to make sure it's not stuck closed.

If it doesn't have that butterfly valve there, try pulling the intercooler tube on the drivers side and starting it. Could be an air restriction.

Ohhh i love these no starts!

9 times out of 10 an aftermarket scan tool will not read all the codes for these trucks. So yes you may get the generic cam/crank sensor codes but you wont get the P0611 your ficm died and went to heaven, The P228X ICP codes, or the GPCM fault codes either.

What i want you to do, get a can of 3M silicone spray. Take your cold side CAC tube off with an assistant, have them cycle the key on. Listen to the injectors clicking away when they stop have them crank it and let r rip on the silicone. IF it fires up stop spraying. If not do NOT over load it. Quick shot and it should fire up by quick i mean press the nozzle down for like 2-5 seconds.

If it fires once and "the fire wont stay lit" you have a ficm issue. If you have no start at all-high pressure oil system issue. Yes they will not fire even with silicone spraying down their throats with a high pressure oil system failure such as a dummy plug disintegrated or an STC fitting which blew apart....


Start checking the easy/obvious first. OIL LEVEL-Very critical. If its low enough they will not start. Oil contamination-If you have a ruptured cooler and have coolant in the oil it will mess with the oils viscosity. May start, may not more so not.
No starts will also happen if the EGR valve is stuck wide open, sure there may not be a fault code set for EGR position/error, but i have seen enough of them in 6.0s and 6.4s to cause them not to start at all. Pull it out and see if it starts IT WILL RUN EXTREMELY ROUGH!!!

If you have an electrical gremlin like say a fan clutch harness... Wouldnt be surprised. Some of them will cause a 6.0 not to start. Crank and crank and crank. No start.

The likeliness of a compression issue is very little.... Its not a 6.4, these dont melt pistons. To be sure of this take your oil fill cap off and have someone crank it, if you feel alot of air you have a definite issue. Even if it is suffering from a compression issue to the tune of a missing/damaged piston it still should start and run. Key signs of this will be oil reeks of raw fuel, very thin consistency. Almost watery.

Was the truck running after you did the fuel filters?
What other issues are you having, like was it losing power before hand? It seems to me you have a FICM issue and the scanner you are using isnt capable to see this. (My MAC tools scanner doesnt work for shit on diesel anything)

Please help!!!! We attempted to repair the ficm per the instructions on this website and now the truck will attempt to start but will not. It turns over but will not start. Before the repair it would not start if to cold and had to be plugged in. It gives the ficm code and fuel injector code on the bullydog monitor. What next?

Most of the time you can get it started by just keeping the key turned till it starts, don't let off when you first hear the fire, let it get running before you let off key. Youre best bet is to send the ficm out to be repaired, they also test it before it is sent back to make sure there are no other problems with it, they offer quick service because they know your truck is down..

Bob, I've got a FICM here that literally wont start the truck cold, but if you plug it in, it will fire up just fine. I can hold the key down and crank until the batteries die, it puffs out smoke like no one's business but just will not start the truck.

Sounds like it needs a FICM repair.

I know this may sound strange, but my dad's 04 f250 wouldnt start one day. towed it to the dealership. come to find out that if both tail lights are out, it will not start. it was as simple as that. sounds trivial, but worth a shot.

:argh::argh::argh::argh::argh::argh::argh::argh::a rgh::argh::argh::argh::argh::argh: say what!!!!!!!!!!!!!!!!!!!!!

I have this problem with a2003 f450 6.0 . About a year ago the truck shut off going down the road.wouldn't start . had it towed back to the shop where it started up and worked fine until the other day. Drove it to work and shut it off . went to start it and wouldn't start . No smoke , nothing . Any suggestiions ?

That sounds exactly like my story. Ended up being the HPOP. Really sucked. Just like everyone says though, start with your basics and work through the system.

I would be amazed if this is actually true. I wonder if pulling the bulbs will simulate this? If my truck was here right now I'd try this out, I can't imagine this is actually true...

Need more info. When you crank does it puff smoke at all? Could be a high pressure oil leak, a loose connection on the FICM, the FICM itself going out... hard to say. Dealership couldn't find anything wrong? Tried scanning codes at all? (Check engine light does not need to be on for codes to be present). Your no start after hot sounds like a high pressure oil leak, but I can't believe it shut the truck off going down the road.

Typically 03-04 trucks when the HPOP goes out it seems to die a slow death just like he is possibly experiencing, and 05+ for whatever reason seem to die instantly.

X2...so if a trucks going down the road, hits a bump and blows both back taillight the truck dies? Ive got a f350 at the shop that aftermarket bed uses the trailer wiring for lights....it runs.

Yeah mine was instantaneous. Worked one minute and not the next.

took some stuff apart to get to camshaft position sensor . in the meantime I was going to try to start with the silicone spray trick . Tried to start it with nothing and it fired right up .:jump: :argh:

---AutoMerged DoublePost---

Thanks for all of your advice . The truck fires right off with the silicone trick . and sometimes it will fire without the silicone . My guy was unplugging the sensors around the 90 for the charge air and unplugging the the vgt at the turbo. but can't duplicate anything . truck runs great but if you shut it off it won't start unless you give it a little shot of silicone ? I am assuming it has to be a bad harness or connection but I am pulling my hair out . Your post has been most helpful, I have bulldzers and backhoes and dump trucks for over 30 years and never knew the silicone trick .

Mine was the fuel presure regulator, located behind the turbo right next to the fire wall.
It has a screen on it, gets small rips in screen causing the sensor to fail, no start.
There are no codes that will show this problem so I was told.
FICM,ha that problem to try pluging in the block heater , starts lots black smoke you can bet its getting bad.

Know other subject , jecking cold engine 50-60mph , EGR valve and intake pluged.
I used a bit of brake cleaner when engine runing , took intake hose off sprayed it in, then
sprayed, squirted AFT in the intake on warm engine let it sit , start up white smoke some black , done 2x s know no more jerking, no more long warm ups , start and go.
AFT seems to break down the carbon inside the intake , so far so good . Sure better than taking intake off and cleaning it .

No crank no start
 

I was driving down the road this afternoon and my 04 6.0 just died. I pulled over and waited 30 seconds and. Cycled the key to restart and nothing the truck will not even crank over. Help please I just dumped over 4k into this damn truck . I thought I had it running a lot better and it had good power and everything . Then all of a sudden nothing.
