I once had a problem with a marker lamp that would never work, even with replacing the bulb. I replaced a large relay (its real long, biggest one in the fuse box. I think all the outside lights at one point make their way through that relay) and the marker light magically came back on. This may have something to do with it as well.
Get your timing chain and rails done like you should. I would know more than anyone!! The noise it makes when it goes will make you cry.
