I guess fuel starvation or faulty engine speed sensor.

Assume you have confirmed alternator is not seized.

Yes alternator is fine. I had all injectors tested they are fine I took valve cover gasket off and everything is fine.  I pulled all glow plugs they are all fine.  So today it started without cylinder 3's glow plug in!?!?!  I'm very frustrated!!! I know it's getting fuel but am wondering if my SAM is making cylinder 3 injector stay open!?!?  Help!!

Uncle Sam does not control your injectors.

or crank sensor...or wiring issues

 

seems weird to say it doesnt run and then say it runs with cyl 3 glow plug out

 

i have no idea what would cause that

Was thinking the cylinder without glow plug was filling with fuel.  Without constriction it fires right up.

filled with fuel would hydrolock it

 

wouldnt take much either ..the combustion chamber is tiny in these things

When you had valve cover off, did you confirm each valve opens by turning engine be hand?

I think a mechanical problem and neighbour mechanic no good. 

 

Suggest you remove valve cover. Check timing. Turn engine by hand and confirm valves do open fully and that there is no problems with followers and hydraulic tappets.

Just curious.

How did you have the injectors tested?

and

shouldn't diesel fuel be pissing out of the removed glow plug hole when you cranked the motor or when it ran for a few seconds?

Out of curiosity have you confirmed you have no significant restriction in the intake? Easy way to test it i sto just remove the rubber hose from the EGR to the intake manifold. 

If the EGR is full of carbon to the point of restricting too much airflow, the motor will start but as soon as it starts to draw a vacuum you lose compression and it will quit. Weird that it would run with #3 GP out though...

Anyway, something to try if you haven't already, and a very easy test.

Why are you answering the question for Jerry? Why would you pull the heads off if you have a start and shutdown symptoms?

Only remove head if there is a real reason for removing it like changing valves or leaking head gasket etc.
