oil cluster or gauge reads zero

Oil level is not the same as oil pressure. Make sure you have oil pressure before operating the engine. -- It could be a bad oil pressure sending unit. It could be a bad gauge cluster. It could be no oil pressure in the engine.

thank you, is there a way to check for oil pressure,and is it possible that after jumping the battery i could have messed up a fuse, after taking off the oil filler cap while engine is running should i see oil free flowing over the rocker arms

oil pressure reads 65psi when you turn the key on . After starting the engine it still reads 65 psi.
