1991 Toyota Hiace Engine: 3L (2.8 litre) diesel, manual Chassis: LH123 Mileage: over 500 000kms
We had the above vehicle sitting in our yard for nearly a year, until the decision was made to recondition the engine. The engine was out and in pieces for many months, and the van was pushed around the yard a few times to clear the parking spaces. Each time, it left a deposit of power steering fluid on the ground.
Anyway, I rebuilt the engine a couple of months ago, and refitted it early December, but for some reason, the P/S pump just won't pump. P/S was working OK when the vehicle was driven off the trailer.
The system was bled many times but to no avail. At full lock, you can't hear any pressure relief valve or cavitation noise, nothing. The belt seems to be driving the pully, yet it feels like the pully isn't driving anything. No swirling in the reservoir. Before I do anything major, what do you guys reckon the problem is!

Sometimes with the engine running at a decent rpm (3000) give the rear of the pump a few cracks with a hammer and they may come free.

Assuming the reservoir is remote from the pump. a mason bee has built a nest in the supply hose going to the pump, or even on the outlet could cause a airlock and prevent fluid getting to the pump!

Thanks very much for all your advice guys. Half a dozen whacks with a hammer got it sorted. Worked a treat.
No mason bee nests in the lines either, which is good.
