Your gauge or sender unit is likely to be faulty 
If it has no oil really, its to late

only know GQ senders and gauges are crap, never worked on GUsPosted: Mon Oct 06, 2008 8:18 am
oil was only trickling out of the sender we thnk it was the reason the cam shaft broke ,at idle the guage did not read 10 psi , to scared to rev it would rather pull it apart again

Yep GU is a light only, no gauge, maybe Nissan gave up as they couldn't build a decent gauge. Camshaft breakage is a sign of no oil or a seriously warped head, I've got my old 2.8 on ebay siezed and all, it's up to $405
