Nissan Largo Friends

Hi all. Thanks for the acceptance. I have recently purchased a largo.done a bit of welding work on to get through the mot. However taking it for the mot it seemed to kick down gear hard and it snapped the ignition pump belt. Now i cant get the van to start at all. Ive put a new belt on but cant seem to get the position of the pump pulley timing mark right. Anyway nice to see people who are keeping these lovely vans on the road. I love it. Even more if it actually moved off the drive

I'm not much help with the diesels I'm afraid but perhaps someone else might know...
