My oil pressure guage has stopped working. It doesnt even move when i turn the key on. What is the easiest way to check it to see if it is the guage or something else.
Thanks

Check the wiring at the gauge and sender first. If it looks good, then get a known good gauge or replace the sender.

take the wire off the sending unit, ground to the block with on gauge should go all the way over, if does not ck wiring back or gauge is junk..
