2001 2.7 CRD Jeep Grand Cherokee
 

Anyone here can give me specific information upon what the pressure inside the common rail should be upon starting and how much pressure should remain in the common rail after stalling the engine.
Have one that starts up real bad, sometimes does it good, diagnostics showed bad common rail pressure, upon stalling pressure drops to 2,5 bar, while running does round 300 , however upon cranking pressure gets up real slow ( 10-15 sec to reach 140 bar, or cant reach at all)
Some sources have claimed that this is normal, however I am doubting it, hoping to get some answers here.
