[QUOTE="Fishfiles, post: 7207, member: 782"] I will usually check for voltage at the glow plug with a test light on the bar that runs from one to another and feel the head of the glow plug with a wet finger after holding the glow plug on , and you can pretty much tell if they are getting hot or not ----but I am affraid that you hard starting is most probally a compression problem , especially since it has become a starting fluid addict ------ it's a good time to check the compression when the glow plugs are out , if you don't have the adaptor to check the compression thru the glow plug holes and you or some one you know welds you can take the old glow plug and cut the top off with a hack saw or grinder and use a punch to punch the electrode rod out the center , leaves a perfect hole right thru the threaded tube , then weld ( preferabally Tig weld or acctylene braze ) a fitting which will connect to a compression tester to the glow plug and you have a adaptor , don't have the book in front of me but seem to remember the compression should be well over 400psi , something like 475 and no more than 10% difference between any cylinders , under 400 and it will probally be hard starting good luck [/QUOTE]
