that compression should be enough to start, if it was me i would un plug the glow plug system and give her a little sniff of either but if you do that and its not really advised but un plug the glow plugs!!

Welcome to OB!

Those numbers aren't too shabby depending on the mileage of the motor.

Questions are:
Is the glow plug system operating?

Are the glowplugs in good working order?

When are you having starting problems?
First thing cold start?
Starting issues after the motor is warmed up?
