Hi, i bought a brand new forged 5efe a couple week back and only just got the engine in. The mechanic doing the work turned the engine over with no sparkplugs in just to check for pressure and the light never went off. He removed the oil pressure switch, turned it over but no oil came out. He plugged a gauge in and read 0. He took the sump off just to look for an obvious sign but nothing stands out. Does anyone have any idea at all what it could be. Its had a genuine toyota oil pump on it and pressure relief valve cleaned and reassembled before i bought it. As i say its a brand new build and need it running asap. If anyone can help i would be very grateful cheers
