ive removed them all from the engine & plugged them back into their sockets & ran an earth wire to there bases & turned the key , none get warm . Stuffed a test lead probe into a terminal that feeds the glowplugs & theres no voltage present although i may not of made proper contact . Is there a common cause for these to stop working . Cant see a fuse that powers the glow plugs ? where do i go from here
