So I have been absent here for awhile, mainly due to my truck not giving me any issues, but that has changed as of recently. 1987 F250 6.9, auto FWIW, I had an issue with it not starting, so I replaced all 8 glow plugs with the motorcraft zd9's, truck started better than it ever had, for about a week. So what happens now is, I turn the key on, let the glow plugs cycle, light goes off, with no clicking sounds anymore, as I had before I replaced the glow plugs, but it won't fire without ether. May this be an issue with the relay? I will do some searching about how to test a glo plug relay, but I figured I would explain my situation here first. Thanks.
