OK, why do you say it has no oil pressure?

Put a proper gauge on it, don't rely on the low oil warning on the dash as maybe you have faulty wiring.

The other issue is that Holden V8 engines is that they can have priming issues on first start up. Fill the oil pump with vaseline and fill the oil filter before fitting. It's a little messy but it helps to get the oil pressure up quicker.

I had a 308 that had no oil pressure after doing an oil change. Tried a new pump etc but still no go, we pulled the engine down and didn't find anything. After a quick freshen up it all went back in and had oil pressure. The only difference from memory was that we packed the pump with vaseline after the rebuild.

Yea packed it each time I replaced or even taken it off.. theres no oil in thetop end at all

Seems very strange that you get different engines with identical problems.

You say you freshened up both engines. Did you change the gasket for the oil pick up, sure it's bolted down securely?

or is there a small gap in the pickup somewhere??

Well after another oil pump an the 4 oil switch I have pressure but now code 19 and 33 are apearing anyone have advice on them??

Code 19 - Throttle Position Sensor (TPS) - Stuck Open

Code 33 - MAP Sensor Signal - Voltage Too High

Any idea on 33 coz I have no idea

Try a different map sensor.

It's either the sensor or the wiring, usually the sensor though
