Where are you located?

Try this.....under the coolant reservoir where the drivers side valve cover is, unplug the two big connectors. Key on, engine off. Then, plug them back in. If the truck fires immediately after, you have trouble with the ficm. This is common if your base battery voltage is below 10 during crank....you may have fried it....

Yeah the 6.0 is a chain reaction kind of motor. Bad batteries kill FICMs, bad FICMs, kill injectors. Also Bad oil coolers kill EGR coolers, bad egr coolers blow head gaskets.

California, I try that tomorrow after work. One question though, you say if the truck fires immediately after... its ficm. What if it dont start?

We go through sinister for erg delete....good move no matter what.

Arp and onyx gaskets for the heads.". He'll...damn torque wrench for this job was over 600bux.....

Cast hpop sucks. Aluminum one rocks.....Looks homemade....but way better....from ford...only....

We perform a buzz test prior to disassembly. Then, cab off and go!

The local ford dealerships use three of us in swfla for 6.0....and I sure am happy about that!

Once cab off, I put 450psi nitrogen throuh hpos....it Tells me if it Its a dummy plug, stand pipe....hpop....random oring......

Anyway....gimme a shout...

FYI....I do fleet for fedex, christo and several others....plus the stuff that comes from ford and by rep.

commandersander 12-16-2012 09:26 PM

If it does not, then the list goes as such...

Low hpop psi.....or....below 450++ to start....hot...cold....whathahellevah

What filter? Motorcraft? No? Issue...

Oil filter at front of engine, behind front curve of intake.....not full?

Psi switch in pan.....stuck?

Coolant bottle.....oil in there? Diesel?

Where are u?
 
Still interested in the unplug and plug in result.....

I have read that the Onyx gaskets are garbage. There have been numerous falures from guy on powerstroke.org. Most people there run OEM gaskets with ARPs.

One thing to remember when dealing with those diesel forums is the guys with those failures, don't belong changing there own oil Nevermind a head gasket job.
