LOL--and from the way this bunch sounds they probably cranked it for one compression stroke per cylinder instead of 5(?) I think it is, just to give you some numbers.
Could you please explain this in more details I can't understand what you mean "they probably cranked it for one compression stroke per cylinder instead of 5(?)"
the dealer say that 200 PSI is good but lower than this not acceptable..... I will do the Perform manual compression in other shop to be sure... what is the right procedure to do the Perform manual compression. As I reply before the engine want to start after long cranking but it stop after one cycle ….does this indicate that the fuel flow not enough to start the engine should I change the fuel filter?

It means that that for EACH cylinder the compression gauge should be screwed in and the engine turned over 5 times. The compression on this diesel engine should not be much under 350 psi for each cylinder to run correctly.

thank for your explanation but, I wondering that the dealer does not applying the procedure test .... I read one article about this subject it say that "Warm up the Engine until the coolant temperature reaches 75<SUP>0</SUP><SUP> </SUP>C to 85<SUP>0</SUP>C prior to do the test" if the engine cold and not run for a time does this mean that the test compression done by dealer not accurate

It could be lower than I told you cold, but it will still have a LOT higher than what the dealer tested hot or cold. It's not going to be 1/2 of what it should be cold or it would never start. Even a new engine wouldn't be 1/2 of what it's supposed to be (400-420) and be able to start. In some cases it may not be able to start the engine to warm it. This is your case.

I would like to clear one thing the compression test done under cranking, because the engine won’t to start..... I will repeat this test after the engine run
what I should do to start it , yesterday I remove the EBP connection the cranking improve but it not start also I remove the EGR but no improve. I will test the FICM today if the result is ok what is the next step?????????

I test the FICM as per the PROCEDURE for 4 SCREW FICM
1a. Take a multi-meter set on DC volts and connect the ground lead to battery negative, and with the key ON measure the voltage at the screw on your right—closest to the driver’s side fender. Do not let the probe short against the case! The voltage should be right at 48 volts. Anything between 47 and 49 is good.
1b. Have an assistant cycle the key and measure the voltage during the initial key-on buzz test. Voltage should not drop below 46 volts.
2. Next measure the voltage while cranking the engine. If voltage stays at or above 45-46 volts, the FICM is fine. Abnormally low battery voltage can give a false low FICM voltage reading, so make sure your batteries are good.
the result in (1a) 48v , 11v, 0v & 0v the result in (1b) 48v , ?, 0v & 0v the result in (2) 48v , ?, 0v & 0v
(?) I can't remember but I was less than 11v .... does this mean FICM not good and need to change.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-comfficeffice" /><o></o>
Yes the FICM is bad and needs to be replaced before any further diagnosing..
can I repair it ?..... If yes, from your experience what I should trace in the board circuit ... usually what components are damaged on it ..... Do you have any support on this such as FICM procedure repair , you tube ... presentation .... artical....
Also I'm seeking a support from all….. any one repaired FICM can help me on this
