If you have a glow plug for each cylinder, they HAVE to work if you want normal starting. If you get the glow plugs working and still have hard starting with no significant blowby, battery, cables and starter are the next suspects. Battery must be high quality, DIESEL-rated. The important rating for gasoline car engines is 'cold cranking amps.' For diesel engines it is 'reserve minutes.' The difference is usually very obvious in the weight of the battery, the diesel battery being much heavier, of course. Not only does the diesel crank much HARDER because of the extremely high compression but it must crank much FASTER to build enough heat in the cylinders to ignite the fuel. Thus the need for a battery that can produce awesome power and TORQUE at the starter.
