Can you borrow a known good FICM (programmed) from someone?

That is another step that is right down the line.

 

Ya... I'll go through the "easy" ones, and check'em off as I do them.

Nope. I don't know anyone with one available as spare. However, several family members have 6.0s ...getting them to allow me to pull their "working" truck apart, is another story. Even my Dad has one.

 

You are getting no coders?

How about a complete systems reset?

Are your batteries fully charged? Voltage while cranking? Glow plug on?

 

No code reader, tool in hand today. Maybe tomorrow.
... I DO have a voltmeter, test light...etc. Never needed the code reader (Ex was under warranty).

By pulling the batterys for some amount of time? Did it already.

Yes, Yes, Yes.

 

Is the CEL light on?

What is voltage of batteries? While cranking?

Low voltage / bad batteries can cause FICM failure, also no start.

You need to be charging them after so many start attempts.

Is there a fuel heater in the HFCM? Have you tried disconnecting it?

 

No (but I also know it can still throw codes and not be illuminated)

Great (I'll check with a voltmeter tomorrow), but they are fairly new and have been able to start the truck with NO PROBLEM before today. Did you read this truck had shut off on me... twice before, when driving? That wouldn't be a low battery or troublesome battery problem I'd think.

The charger is on the batterys (mentioned this a few posts ago)

Fuel heater... hmmm, not sure. I'd have to check. Being it's in Cali... you think it'd come with one from Factory?

 

Some time around 2005 fuel heaters were discontinued, but on my E, there is a heater.

You need some basic diagnostics tools to move ahead.. code reader... volt meter...

 

Non of the symptoms mentioned by the OP relate to the fuel heating element- which his unit may or may not have.

He is in San Diego people...

The random nature of the problem suggests an electrical issue rather than a fuel supply issue- this does not sound like starvation because it is sudden. While lacking the expertise of Cheeseit, it does seem familiar to symptoms of a bad cam position sensor.

Electrical / FICM / chafed wire is down the check list.

If he does have a fuel heater, I have noticed problems with starting that was resolved by unplugging it.

It comes on, and as best as I can guess, causes a vapor lock.

Doesn't matter if he is in San Diego --- the HFCM / VFCM programs it to come on (if equipped).

 

Well... it's morning here, and time to start trying more stuff (my technical term for troubleshooting)... I've got a car today (my fiance's running Tahoe! ..much better than going to the Ford dealer on my Mtn Bike!)

I'd think my verification that fuel is flowing into the upper fuel filter, and no bubbles... means, no vapor lock due to a fuel heater, if there is one... No?! Or is that too easy of a thought for it to be accurate. (I know pressure and volume are still not verified - however, with no smoke out the pipe... I honestly think, there's nothing (no fuel) getting to the cylinders. But what do I know?!)

I'm going to use my Fluke and test the FICM this morning. I don't have anyone to crank it over while I test however... maybe a neighbor will be available when I'm ready.

... and I agree with Mike that, to me... it seems electrical. Because, it's cut out twice on me WHILE driving. No hiccup... no sputter... however I was off the gas, and coasting into a corner (for one instance) and noticed no power steering and no power brakes. Threw it into neutral, and it started RIGHT back up. Both times. This last time... is it's first time to not start back up. And it's had about 1k-2k of miles put on it since last episode.

If it is a chafed wire... isn't there a bunch of recalls on them? And would you know, where I'd find the recalls per my vehicle...? You can lead this horse to water.... and I'll drink.

 

Check the tech folder for chafed wire photos..

One high on the list is the ignition key wire harness --- apparently that one chafes!!!!

But check every one.


Oh... also high on the list... if you unplug the ICP sensor and it runs...

 

Nope... not the ICP Sensor (thank goodness thats SUPER easy to get to to test)

 

I will drive through San Diego in the morning John rather than on my way back from LA and hook it up to my AE. Hopefully we can get a code out of it.... is 6-7 am ok???

 

Stand-By Arm.... I've got a Ford (Diesel) Mech on his way by after work tonight, to take a look and do a 'quick' inspection. Maybe he'll find something I missed, see a code... or, just be able to wave a magic wand.

... I'll send you a text, or call ya. THANKS for the offer too! Just awesome! I'll buy breakfast if you have the time (if you end up coming by).

 

Have the fella coming by pack a spare FICM.
