Injection pump timing

[billyballard]

I have just fitted a new cam belt to a 1.5 diesel P reg 106. Fitted the locking pins in the Cam Sprocket and the flywheel. I can only seem to find one hole to lock the injection pump sprocket. as there seems to be 2 holes in the pump casing to locate the pin in it means i could get the pump 180 degrees out. is it normal to only have one hole to lock it or am i missing something.
Tried to start it several times and then found that 2 glow plugs were useless. replaced them but still no go. Engine turns over ok but does not fire. (could it be flooded?

thanks in advance Chris

Just Noticed that the pipe coming from the priming bulb thing (dont know it real name) had come loose and has allowed air into the system. Whats the best way to get the air out and prime the pump again?
