Many of you may be having 'hard start' or 'no start' problems with your trucks. #1 cause is the batteries and #2 is the glow plugs and controller. Amazon has several glow plug controllers: https://www.amazon.com/s/ref=nb_sb_...ive&field-keywords=Glow+Plug+Controller,+FORD. DO NOT buy glow plugs from Amazon. Use ONLY Beru/Motorcraft glow plugs! The others can swell in time, and cause major problems trying to remove them, by swelling. The heads may have to be removed if this happens.
Merry Christmas!
