Your timing is out. you need to check the tdc marks align through the top of the gearbox to the flywheel. also remove the rocker cover there is a slot cut into the end of the camshaft you can slide a metal bar into this as it should be level with the cylinder head if it is timed correctly. the diesel pump is aligned with a peg or drill bit through the pump drive sprocket. Hope this Helps.
