Land Rover Santana drowns when starting

Hello colleagues, I have a LAN ROVER Santana Super 88 Special Series 3 of the year 83 Diesel. For a few days I am giving me a problem when starting it, and it is drowning and stops. Once underway without compression problem or anything. I have noticed that priming it a little before it costs you less work, but still giving the failure, I don't know if there will be any problem to bomb nibel, injectors ... some council .... Thank you beforehand

Problem solved, like Juan Palomo, I stepped on it and I like it. There was a drilling in the sleeve that goes from the diesel pump to the filter (air inlet into the circuit and loss of diesel) so it cost to start. As always the technology of these Santana is simply perfect, after 29 years rolling throughout Spain, the fattest problem that gives is the perforation of a sleeve. Explain that to my other car "Patrol Y61 2006" From here to 29 years ... hehehe
thanks anyway
