glow plug WT*?
My cousin got a 1995 7.3L. bought it last year does not use truck much but to pull camper around. so has long periods of none use time.
well late in the year glo plugs stopped working. timer light on dash still seems to time out like timer is working but wont start without small ether shot.
well decided to replace glo plug solinoid last friday. truck sat outside night b4 and temps in the 30's. changed solinoid turned on key light on dash timed out and behold like magic fired right up. did same all day friday and saturday. well come sunday morning was ready to return home from deer hunt and truck wouldn't start again. small ether shot again started right up.
he said he replaced the solinoid with a standard ford solinoid from auto parts store. like from older ford starter solinoid as it looked like the one he took off. my question, is the glo plug solinoid different from the the starter solinoid?
if not what else can be the problem? Thanx,
Jay

glow plug relays and starter relays are very different, but one problem is that most auto parts store's glow plugs realys are not worth a crap, I have heard people have decent success with a NAPA gold relay, but alot of people change to a stancor continuous usage industrial relay, if he just used a normal starter relay then he needs to change it back, and as a side note, don't use ether to start a diesel, you will damage it and you will be worried about alot more than just a glow plug relay, use wd-40 instead

^^^ if the diesel has glowplugs. If not ether is just fine. What happens is that when the ether hits a hot GP it will ignite, so on the intake stroke as soon as air-ether gets pulled in it ignities and burns back through the intake system to the source. In extreme cases, the air intake box will blow up. LOL. I would think WD-40, wouldn't be good either, but don't know for sure.
