Welcome to CsC.

Thanks excited to be here

I guess fuel starvation or faulty engine speed sensor. 

[tolsen 630]

Assume you have confirmed alternator is not seized. 

[Jeff123456789 0]

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!!

[tolsen 630]

Uncle Sam does not control your injectors. 

[tolsen 630]

And why remove valve cover seal?

[Jeff123456789 0]

Wanted to check valves and cam

What controls injectors

[LooseLugNuts 557]

probably the ecu beside the airbox (but thats just a guess)

[Jeff123456789 0]

I think if that controls the injectors may be it?!?

[LooseLugNuts 557]

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

[Jeff123456789 0]

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

[LooseLugNuts 557]

filled with fuel would hydrolock it

 

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

[tolsen 630]

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

[Jeff123456789 0]

No I cranked it while my neighbour who is a mechanic checked each one

[Jeff123456789 0]

Either electric problem or maybe the head needs to come off to be sure. 

[tolsen 630]

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. 

[Jeff123456789 0]

Got the injectors tested by a fuel injector tester with a Bosch machine. 

[booneylander 37]

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.

[Jeff123456789 0]

Gonna try that then if that fails going to remove the head!  Have to find the thread on timing

[tolsen 630]

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

Update

Pulled back assembly out. Took off chain cover and the oil pump sprocket had no teeth left.  Then took off head and head gasket was also gone.

A smart engine.  Smart enough to tell you it was not well!
