Hi there,

High volume pumps are a bit of a trap on Holden V8's they tend to flood the rocker cover and you start to get a bit of oil consumption if you have suspect valve stem seal and guides, anyway, no oil pressure will be a faulty pressure relief valve or air sucking in the pick up via a cracked pick up (known to happen) or loose bolts on the pick up. these pumps don't loose prime once they have had oil in them, so the pump it self should be ok....
