My diesel has got a strange cold start problem,
It fires up perfectly every time then it runs for about ten seconds and cuts out.
Then its a real pig to start, it does start but not without a fight and spitting out alot of smoke.
are you getting several clicks from the pump when you turn ignition to position 2? could also be worn out glow plugs or poor battery or timing out or air in the system or poorly fitted fuel filter or the diaphram in the primer pump.
