Im just about to start my new renovated engine.
But my new electric aftermarket gauge doesn't show any oil pressure (so I’m afraid to start it) i’ve disconnected the fuel pumps relays and the spark plugs are out. When hit the ignition, the needle jumps up below 0 (check picture) and when I crank the engine it goes to the bottom like it should since it’s attached on the radio fuse. But when I let go of the cranking it jumps below 0 again (I’ve tried to crank it for 10 sec x5 or more times) but no results. Do I have to start the engine to notice oil pressure on the gauge? or can I make sure I got oil pressure without the gauge somehow? Or can I do something to build pressure at first?
If it is an electric gauge then yes you will have to start it before you see the pressure. Did you prime the oil pump before you tried to start the motor?

It’s a oil pressure sensor that I installed in my sandwich adapter, with one “S” wire to the meter, and one ground (And of course a + and - from the meter to ignition)
And I haven’t had the guts to start it yet, just tried to prime the pump due to cranking the engine over for small intervals (10 sec x5~ times or more) but since I don’t notice the meter move above 0 I’m afraid to actually start it.

Here is what I would do. Set timing to tdc and lock the cam gear and pull the timing belt off again. Take a drill bit and a 14mm socket and spin the oil pump pulley This will prime the motor without having to start the car. You will know that the motor is building oil pressure because if you remove to oil cap you will be able to see oil coming out of the lifters. You may have to do this for a few minutes before you start seeing oil come out the lifters but once you see it you will know that the motor is properly primed. DO NOT USE AN ELECTRIC IMPACT to do this make sure it is a drill. The hammer that impacts do can destroy the teeth on the oil pump gears. If the oil never gets to the lifters then you know you have and issue and your motor isnt building oil pressure.

Alright, im about to follow your advice. But I can’t manage to get the crank pulley off. Seems it’s stuck on the crank even tho I’ve removed the 4 bolts. Do I have to remove the big center bolt as well? Any ideas?

Yes that will also need to be removed to get the Harmonic Balancer off. If you have access to air tools or electric impact i would start there. I have an 1/2 Milwaukee impact that I usually use to remove it.
he doesnt have to remove the centre bolt toa take the harmonic balancer off... Just take the cambelt off and spin the pump with the dril... Then take care to reinstall the cambelt with the pump and front ballance shaft timed the right way.
