yeah my dam oil pressure gauge stop working and right now i don't know what happened. i change sensors and i check the wire for cracks and i didn't found nothing and the gauge doesn't read right. it said that i have 0 PSI in idle and 20 psi in 3k RPM wich it have more than that because i checks my self for pressure in the oil lines and sprayed everything with oil because it have pressure in idle and if i didnt had any pressure i would it locked the engine three days ago. any ideas of what to check? thanks

Ground the sender wire, your OP gauge should peg high. With it disconnected it should read zero.
