I don't blame ya.

PS, silicone spray is probably not going to get it done. Carb clean or brake clean is what I usually use. I've also used ether a bunch of times without issue.

Re: Not your typical crank no start

Certainly lots of people use starting fluid/ether on their diesels, but some have created serious problems.

I won't recommend it on the internet for liability reasons. Some people have even blown the tips off of the glow plugs by using too much.

See post #13 from a well respected Ford Tech.
If not ether , what have you used to start a diesel? - Ford Powerstroke Diesel Forum

As far as being a control issue .............. a control issue will not leave residual gas pressure on the secondary filter. The hissing and spray seems to indicate gas being present since liquids are non-compressible.

From his posts, he certainly could have a control issue as well.

You really should do the bubble test before giving up. You don't need to isolate the fuel rails at this point.

Re: Not your typical crank no start

Ether washing the cylinders? What a joke. That must have been a lot of ether. I highly doubt he's ever actually seen that before.

Re: Not your typical crank no start

Ok, back with an update.

Bubble test PASS. 0 bubbles noted/found.

I'll check the fuel cutoff switch and FICM fuse/relay next..

Does anyone happen to know the exact sequence of the FICM buzz when you turn the key? I still think I have a fuel control issue.

Don't bother with the cut off switch, you already know its getting fuel. And Failed o rings wouldn't cause this.

The sequence is different for different years. I've heard some that just buzz solid, and some that buzz all of them, then buzz each one in sequence of cylinder number, then buzz solid again. But if it doesn't sound right, then it's probably not. How many years have you been listening to it? You would know if it sounded different.

You need to figure out if it's commanding fuel or not. All other tests are pointless or redundant right now. Except a shot of supplemental fuel, that should be done also.

What is causing his hissing and spraying from the secondary filter? That clearly is not typical and is not a fuel command issue (or lack thereof).

Also, if he has FICM sync, it should be commanding fuel shouldn't it? ... especially since he still had these problems with a known good FICM.

I thought that the question was asked previously about any exhaust smoke when cranking, but didn't find it. If there is white and/or whitish-blue exhaust smoke when cranking, then you are getting at least some fuel to the cylinders.

I also wonder if checking another code reader might help. Some are not great at picking up all the codes.

As far as "ether" goes, all I said earlier was to be careful and that I won't say to use it. That being said, supplementary fuel certainly CAN BE helpful in troubleshooting, and brake cleaner or carb cleaner would be better choices.

Re: Not your typical crank no start

I think it probably is a command issue, but we need some data to confirm that, or a labscope. Hissing from the fuel housing? Not really sure, maybe the key was on or something. But we knew it wasn't injector seals because the symptoms didn't match. So I disregarded that.

The ficm runs the fuel injectors. But remember, all sensors go to the pcm. The pcm then tells the ficm when to open injectors and for how long. Basically, there is no need for the ficm other than they must not have wanted to build the boost circuits into the pcm. For whatever reason, they wanted a separate module to control the high voltage circuits. That's changed by the way. Ford now does everything with the pcm like every body else.

Re: Not your typical crank no start

Yesterday when I did the bubble test, the secondary filter did not hiss and was not pressurized.

I tried supplemental fuel and nothing. When it's turning over I'm not getting any smoke.

Is there a way to test the PCM?
