Cool Annual glo plug replacement!!!

What is causing my glo plugs to fail in one year or less. Yes I have checked them with an ohm meter so it is not GP relay.

You said you checked the glow plugs with an ohm meter. What readings did you get?

They certainly shouldn't be going bad annually. I would guess they are not use motorcraft plugs. or the under valve cover harness is coming unplugged.

If they are not motorcraft brand they probably will go out annually...they are the only ones that will stand u to the abuse.
