Oil pressure gauge reading 0

[Paulcovy]

hi all I've recently rebuilt my v8 new shells piston rings cam lifters push rods ect .... finally got around to starting it for the first time ... I primed the pump before hand until the oil lamp went out and I could see oil had filled into the rocker box... as it fired up I was expecting the gauge to rise as it worked before the engine was removed ... however it did not the transmitter was new about a year ago and the wiring is the right way around ... I've read that by earthing the wire the gauge should rise on the 4 cylinder .. is this true on the V8 ?? Because it does not when I try it ... I'm yet to test the continuity between the gauge and the transmitter .. is there anything else I should check that I might have over looked ? Cheers all

Hi Paul.
Yes if you earth the oil pressure gauge wire it should read 60 psi
I did have one car once with a intermittent reading and when the wiring was checked found high resistance in the round multiplug which plugs into dash assembly.
