1G 0 psi cranking oil pressure after remote located AEM gauge/sender install

[all black 4G63]

I can't get oil pressure to build or reach the lifters during cranking ( have not started engine yet). I just installed the remote mounted AEM oil pressure sender with SS line.
Has anyone ran into not getting oil pressure to build during cranking? i almost smoked my starter trying for so long.
Could there be a air pocket due to the SS line install?

The SS line to sender is installed where the oil pressure switch was located on the front of the filter housing.
This is a 90 TSI

Thank you for the support!

Is the engine new? or was already running before?
If it's a new engine, did you prime the oil pump and fill up the external oil cooler and the oil filter well? If you didn't, it would take quite a time to fill up the entire oil passage by cranking. You shouldn't crank too long. Remove the timing belt and use an electric drill with a 14mm socket to spin the oil pump sprocket to prime until you see the oil come out from rocker arms and build up some pressure.

If you are cranking it over for initial oil pressure, remove the sparkplugs and as @DSMPT states, it will take a while for a 90 to fill up all of the cooler lines too. I have my sender remote mounted on my 90 and it is fine. I would crack the end of the line into a old oil container and verify if ANY oil is moving. Just as a test.

thank you very much for the response,

The engine is new and has never been started or ran.

I have already primed the oil system by spinning the oil sprocket a long time ago before installing the sender.

Before I installed the AEM sender I could crank the engine with the starter and the oil would eventually make it to the rockers.

I have had this issue before which I found out was due to a missing bolt (alternator through bolt) in the front cover which I assume was causing a slight pressure release not allowing oil to push through the galleys. However, there are no missing bolts this time.

thanks for the replay.

you think cracking the sender line or oil cooler line to verify oil pressure?

Yes.
I would take the sender off and stick the line in an old pop bottle or such and crank it over to see if any volume of oil is present. Once it DOES start to pump, that will fill up so keep an eye on it and if it begins to fill, put the sender back on and you should have some readings start.
