E320 cranking but not starting
 

Hi I have a e320 1999 which cranks but won't start unless easy start is used ( which I don't like using) crankshaft sensor, oil change and filter, fuel filter and air filter have been changed recently. Fuel pressure is ok glow plugs ok. When the car does run its fab, no smoke, stalling, doesn't use more diesel than normal. Could it be a relay issue??

Have you had the codes read? I would start there. How does the starter look? In case it is the starter, take a look at the link below on a DIY procedure to replace it. Best of luck!
